Why Phoenix’s Skyline Has Stayed Low — And How It Compares to Los Angeles
Discover why Phoenix’s skyline lacks supertall skyscrapers, from FAA flight path limits near Phoenix Sky Harbor International Airport to how it compares with Los Angeles’s skyline growth.
Last Updated on March 25, 2026 by Daily News Staff
Phoenix is the fifth-largest city in the United States, yet its skyline doesn’t resemble other major metros like Los Angeles, Chicago, or Dallas. Despite rapid population and economic growth, downtown Phoenix has long lacked supertall skyscrapers — and until recently, didn’t even have a building tall enough to qualify as a true “skyscraper” under standard definitions.
The Basics: Phoenix’s Height Reality
The tallest structure in Phoenix for decades has been Chase Tower, rising to about 483 feet. Under the Council on Tall Buildings and Urban Habitat definition, a skyscraper reaches at least 492 feet — which means Phoenix has technically lacked one — despite its size and population.
A new project, the Astra Tower, is planned to rise around 540+ feet when it breaks ground, potentially giving Phoenix its first true skyscraper.
Airport Proximity: The FAA’s Height Grid
FAA Obstacle Evaluation & Downtown Limits
Phoenix’s skyline constraints are rooted in aviation safety.
📍 Phoenix Sky Harbor International Airport sits just a few miles from downtown.
- The Federal Aviation Administration (FAA) regulates building heights near airports so they don’t obstruct flight paths, require planes to alter approaches, or interfere with climb-out safety.
- In Phoenix, this results in a layered set of height limits that vary by location and elevation above sea level — often measured in feet above mean sea level (MSL) rather than simply building height from ground.
The city’s zoning code divides downtown into multiple contour zones with distinct maximum elevation values (e.g., 1,275 ft, 1,525 ft, 1,700 ft MSL), each tied to how close it sits under airport flight paths.
That means in some blocks you can’t build above a specific elevation even if ground levels are lower — a regulatory “roof” that varies across downtown.
City zoning also explicitly states that no building can exceed the FAA’s airport height limits, even if other bonuses or zoning allowances exist.
Phoenix vs. Los Angeles: A Quick Comparison
Los Angeles: Higher Limits, Different Constraints
Cities like Los Angeles also have nearby airports (e.g., Los Angeles International Airport), but their key business districts aren’t directly under major flight corridors.
LA’s downtown has:
- Taller office and residential towers
- A financial core with dense development
- Fewer FAA-driven overlays because the flight paths stretch past the downtown edge
Los Angeles’s tallest buildings — including Wilshire Grand Center (~1,100 ft) and U.S. Bank Tower (~1,018 ft) — were built where FAA restrictions don’t force low ceilings. FAA evaluations were conducted but didn’t cut as deeply into downtown zoning compared to Phoenix.
Phoenix, by contrast, sits right under approach and departure corridors — leading to consistent FAA involvement in almost every proposed mid- or high-rise downtown.
Economic and Planning Philosophies
Beyond FAA rules:
- Phoenix developed in the automobile era, with vast inexpensive land encouraging horizontal growth.
- Los Angeles grew earlier with heavier investment in centralized neighborhoods and higher density.
- Phoenix’s village plan long encouraged multiple smaller hubs instead of concentrating all growth in one downtown core.
These historical differences mean Phoenix didn’t have the same economic “pressure” to build up — even with zoning that allows significant height if FAA permits are met.
What This Means for Phoenix’s Future
Phoenix still has room to grow vertically — but:
- FAA height contours will remain the ceiling unless flight paths change
- Developers must secure determinations of no hazard from the FAA before going taller
- New projects like Astra show demand for taller buildings is rising
As Phoenix’s urban core densifies and land becomes scarcer, its skyline may yet reach higher — but always within the invisible grid drawn by aviation safety.

The Tuskegee Airmen: The Red Tails Who Fought Two Wars
The Tuskegee Airmen were far more than the legendary Red Tail fighter pilots. Thousands of pilots, mechanics, instructors and support personnel challenged segregation while helping fight World War II—and their achievements helped change the U.S. military.
A Forgotten Genius Special | STM Daily News
They were training to fight America’s enemies overseas while confronting discrimination in the country they had volunteered to defend. The Red Tails.
They became known as the Tuskegee Airmen.
Their story is often reduced to an image of Black fighter pilots flying red-tailed P-51 Mustangs over Europe during World War II. But the real story was much larger.
The Tuskegee Airmen included pilots, mechanics, instructors, navigators, bombardiers, radio operators, parachute riggers, medical personnel, meteorologists, cooks, clerks, control-tower personnel and many others who helped make military aviation possible.
The National Park Service describes more than 16,000 people as participants in the broader Tuskegee experience.
Together, they helped challenge one of the most persistent prejudices in the American military: the racist assumption that Black Americans lacked the intelligence, discipline or ability required to become successful military aviators.
They proved otherwise.
An Experiment Built on a False Assumption
In January 1941, Secretary of War Henry L. Stimson authorized the formation of a Black pursuit squadron.
The 99th Pursuit Squadron, later redesignated the 99th Fighter Squadron, was activated in March 1941.
Because the American military remained segregated, Black aviators weren’t simply incorporated into existing flying units. A separate training program was established around Tuskegee, Alabama.
Flight training took place at Moton Field, while Tuskegee Army Air Field provided advanced military flight training.
What military officials regarded as an experiment would ultimately help demonstrate that the restrictions placed upon Black aviators had nothing to do with their abilities.
More Than Pilots
The name “Tuskegee Airmen” can be misleading if we imagine only the men sitting inside fighter cockpits.
Aircraft don’t fly because of pilots alone.
They require mechanics.
Fuel crews.
Radio operators.
Meteorologists.
Armorers.
Dispatchers.
Parachute riggers.
Medical personnel.
Instructors.
Navigators.
Engineers.
Control-tower operators.
Administrative personnel.
And many others.
Women were part of the Tuskegee experience as well. According to the National Park Service, women worked as mechanics, control-tower operators, aircraft fuselage technicians, gate guards, secretaries and clerks. Three permanent female parachute riggers helped train hundreds of cadets in the proper packing and maintenance of parachutes.
The Tuskegee story was therefore not simply the story of several hundred pilots.
It was the story of an entire aviation community.
Taking the Fight Overseas
The 99th Fighter Squadron deployed overseas in 1943.
Flying Curtiss P-40 Warhawks, its pilots entered combat in the Mediterranean theater, operating from North Africa and later Sicily and Italy.
The Tuskegee program continued expanding.
Three additional Black fighter squadrons—the 100th, 301st and 302nd—became part of the 332nd Fighter Group.
And the man who would eventually command them had already experienced another form of racial isolation.
His name was Benjamin O. Davis Jr.
The son of America’s first Black Army general had graduated from West Point in 1936 after fellow cadets subjected him to years of deliberate social isolation.
Now Davis was leading Black American fighter pilots into combat.
The Red Tails
The 332nd eventually transitioned to the aircraft that became most closely associated with the Tuskegee Airmen:
The North American P-51 Mustang.
The tails of the group’s aircraft were painted red to identify the unit.
The distinctive markings helped produce one of the most famous nicknames in American military aviation:
The Red Tails.
Operating primarily from Italy, the 332nd escorted heavy bombers deep into enemy territory while also attacking ground targets.
Escort duty was extraordinarily important.
American bombers flying deep into enemy territory were vulnerable to German fighters. Escort pilots had to remain close enough to protect the bombers while simultaneously watching for enemy aircraft.
The Tuskegee Airmen developed an impressive record performing that mission.
The Legend — and the Reality
One claim became particularly famous after the war:
The Tuskegee Airmen never lost a bomber they escorted to enemy fighters.
It is an inspiring story.
It also isn’t completely accurate.
Research by Air Force historian Daniel Haulman using wartime mission reports found that 27 bombers being escorted by the 332nd Fighter Group were shot down by enemy aircraft.
Those losses occurred during seven of the group’s 179 bomber escort missions for the Fifteenth Air Force.
But correcting the legend doesn’t diminish their accomplishment.
In fact, the documented record remains impressive.
Research comparing the 332nd with other P-51 fighter groups in the Fifteenth Air Force found that the Tuskegee Airmen lost substantially fewer escorted bombers to enemy aircraft than the other groups examined.
The truth doesn’t weaken their story.
The truth makes their achievement real.
Fighting Two Wars
The enemy wasn’t confined to the skies over Europe.
Black servicemen returned from missions defending democracy overseas while still confronting segregation at American military installations and throughout American society.
This contradiction became part of the broader Double V campaign during World War II—the call for victory against fascism abroad and racial discrimination at home.
Tuskegee personnel repeatedly challenged discriminatory military policies.
One of the most significant confrontations occurred in 1945 at Freeman Field, Indiana, when Black officers protested restrictions that prevented them from using an officers’ club reserved for white officers.
Their resistance became known as the Freeman Field Mutiny.
The confrontation demonstrated that the Tuskegee story wasn’t simply about proving Black Americans could fly airplanes.
It was also about demanding the rights that should accompany wearing the same uniform.
Changing More Than Aviation
The Tuskegee Airmen didn’t single-handedly desegregate the United States military.
But their performance undermined one of the principal arguments used to justify segregation—that Black servicemen could not perform highly technical or demanding military assignments as effectively as white servicemen.
Three years after the Tuskegee flying program began sending pilots into combat, President Harry S. Truman issued Executive Order 9981 on July 26, 1948, establishing a federal policy of equality of treatment and opportunity in the armed services regardless of race, color, religion or national origin.
Military integration would take additional years to implement.
But the old assumptions had become increasingly difficult to defend.
A Legacy Larger Than the Red Tails
The Tuskegee Airmen eventually became symbols of perseverance, military excellence and the long struggle to expand opportunity within America’s armed forces.
In 2007, the Tuskegee Airmen collectively received the Congressional Gold Medal in recognition of their service.
Yet perhaps the best way to understand their achievement is not through mythology.
They didn’t need a perfect combat record to make history.
They trained in a system created because many officials doubted Black Americans could become military aviators.
They went into combat.
They flew.
They fought.
They protected bomber formations.
They maintained aircraft.
They trained pilots.
And thousands of people behind the scenes made those missions possible.
They demonstrated through performance what segregation had attempted to deny.
And among the men leading them was the son of America’s first Black Army general.
His name was Benjamin O. Davis Jr.
His journey had taken him from isolation at West Point to the cockpit of a military aircraft and command of the 332nd Fighter Group.
But his story was far from finished.

The Long Track Back
LA Metro Locks In Vermont BRT Funding as World Cup Results Point Toward 2028
Metro’s World Cup service carried 212,865 passenger trips across eight matches. Its after-action report points to strong demand while identifying bus lanes, shuttle frequency, parking prices, and shade as priorities for future major events.
Last Updated on September 21, 2026 by Daily News Staff
A fully funded rapid-bus project and more than 212,000 World Cup shuttle trips offer two revealing signs of how Los Angeles is preparing for the 2028 Olympic and Paralympic Games.
LA Metro has reached a major funding milestone for one of its most important bus projects while releasing new evidence that transit can move a significant share of spectators during major international events.
A newly issued Metro report confirms that the Federal Transit Administration executed a $149.9 million Small Starts grant agreement for the Vermont Transit Corridor Bus Rapid Transit project on September 2, 2026. Metro now describes the proposed $413.8 million life-of-project budget as fully funded through federal, state and local sources.
Separately, Metro’s official review of the 2026 FIFA World Cup found that its special bus network carried 212,865 passenger trips during eight matches in Inglewood—approximately 20 percent of total match attendance.
Together, the developments show Metro moving from planning toward delivery: building permanent improvements for one of Los Angeles County’s busiest bus corridors while applying lessons from the World Cup to the much larger transportation challenge awaiting the region in 2028.
Vermont Avenue BRT moves closer to construction
The Vermont Transit Corridor would create a 12.4-mile, all-day bus rapid transit route between Sunset Boulevard and 120th Street. It would connect with the B, C, D and E rail lines and include 26 enhanced stations at 13 locations.
Metro’s existing Vermont Avenue service carries approximately 38,000 weekday boardings but operates through some of the region’s most congested streets. The BRT project would add dedicated side-running bus lanes, upgraded stations, improved lighting, transit-signal priority, real-time arrival information and pedestrian-safety improvements.
Metro estimates that the project could attract approximately 12,000 additional daily riders while improving the speed and reliability of every bus operating through the corridor.
The funding package includes:
- $149.9 million from the FTA Small Starts program
- $106.34 million from the federal Congestion Mitigation and Air Quality program
- $81.06 million from California’s SB 1 Local Partnership Program
- $44.49 million in Proposition C funding
- $25 million from Measure M
- $5 million from the state Transit and Intercity Rail Capital Program
- $2 million in federal Community Project Funding
Metro anticipates authorizing and executing additional early-work packages beginning in the fourth quarter of 2026. Major construction is expected to begin in fall 2026, with passenger service targeted for June 2028—just weeks before the Olympic Games begin in Los Angeles.
That is a more precise schedule than earlier project information, which described construction as beginning in late 2026 or early 2027 and service starting generally in time for the Games.
The $413.8 million life-of-project budget still requires final Metro Board approval. The federal grant agreement, however, removes a major financial uncertainty and gives Metro a clearer path toward construction.
World Cup transit carried one in five spectators
Metro’s World Cup after-action report provides the most complete picture yet of how the agency performed during its first major test ahead of 2028.
Metro deployed 300 buses over 15 special routes connecting SoFi Stadium with rail stations, transit hubs and temporary park-and-ride locations across Los Angeles and Orange counties. The service carried 212,865 passenger trips over eight matches, including 31,536 trips on the busiest match day.
According to Metro, the operation recorded no missed trips caused by mechanical problems, no traffic incidents and no safety incidents. The agency reported 100 percent fleet availability.
Customer surveys were also favorable. Metro said 91 percent of special-shuttle riders were satisfied with the service, while 93 percent indicated they would likely use a similar direct-service option during the 2028 Games. Perceived safety received a 96 percent satisfaction rating.
Contactless payment played a significant role. Approximately 72 percent of World Cup shuttle riders paid directly with a contactless credit or debit card—a systemwide feature Metro launched shortly before the tournament.
The operation was not without lessons. Riders and participating agencies identified several areas needing improvement, including dedicated bus lanes, more frequent shuttles, lower park-and-ride prices, additional shade, better group-payment options and more seating for passengers with accessibility needs.
Those concerns become more consequential when looking toward 2028. The Olympics and Paralympics will last longer than the World Cup, involve substantially more events and disperse spectators across venues throughout the region. An operation that succeeded for eight matches must therefore be expanded without disrupting everyday bus and rail riders.
A glimpse of Metro’s 2028 strategy
The Vermont BRT and World Cup results represent different sides of the same challenge.
The BRT project is a permanent investment intended to improve everyday mobility in East Hollywood, Koreatown, Exposition Park, South Los Angeles, West Athens and Westmont. Its Olympic value is important, but its lasting value will be measured by whether buses become faster and more dependable for the thousands of residents who already use the corridor.
The World Cup service, meanwhile, demonstrates that direct event shuttles can persuade a meaningful share of spectators to leave their cars behind. It also reveals the extraordinary staffing, equipment, coordination and street priority required to make those services work.
Metro has now shown that the model can succeed at World Cup scale. The next test is whether the agency can complete projects such as the Vermont BRT on schedule and turn a successful temporary operation into a repeatable regional system for 2028—and beyond.

Benjamin O. Davis Sr.: The General Who Broke the U.S. Military’s Color Barrier
Benjamin O. Davis Sr. rose from the ranks of the Buffalo Soldiers to become the first Black general in U.S. military history. His remarkable career spanned roughly 50 years and helped challenge racial barriers inside a segregated Army.
Forgotten Genius Fridays | STM Daily News
Before the Tuskegee Airmen challenged segregation in the skies over World War II, another barrier was being broken within the ranks of the United States Army.
His name was Benjamin O. Davis Sr.
On October 25, 1940, Davis was promoted to brigadier general, becoming the first African American general officer in the Regular Army and the U.S. armed forces. His promotion represented an extraordinary milestone in a military that was still officially segregated.
But Davis’s story didn’t begin with stars on his shoulders.
It began more than four decades earlier.
From Volunteer to Buffalo Soldier
Born in Washington, D.C., on July 1, 1877, Davis entered military service during the Spanish-American War in 1898, serving as a temporary first lieutenant with the 8th United States Volunteer Infantry.
After that unit was mustered out, Davis made a consequential decision. In June 1899, he enlisted as a private in the Regular Army’s 9th Cavalry Regiment.
The 9th Cavalry was one of the famed Black regiments whose soldiers became widely known as the Buffalo Soldiers.
Davis quickly advanced through the enlisted ranks, becoming a corporal and then squadron sergeant major. In February 1901, he received a commission as a second lieutenant of cavalry in the Regular Army.
His journey through the ranks had begun.
Serving an Army That Wasn’t Equal
Davis would serve his country for decades, but his career unfolded inside an institution constrained by racial segregation.
Assignments available to Black officers were limited, particularly because military practices sought to prevent Black officers from commanding white soldiers. Davis consequently spent portions of his career teaching military science at historically Black institutions, including Wilberforce University and Tuskegee Institute, and served as a military attaché in Liberia.
These assignments were important, but they also reflected the racial restrictions under which Black Army officers served.
Despite those obstacles, Davis continued advancing.
He became a lieutenant colonel in 1920 and a colonel in 1930.
Then came 1940.
A Star That Made History
On October 25, 1940, President Franklin D. Roosevelt promoted Benjamin O. Davis Sr. to brigadier general.
For the first time, a Black officer wore a general’s star in the Regular Army.
The significance extended beyond Davis himself. Black Americans had served in the nation’s armed forces from its earliest conflicts, yet the highest levels of military leadership had remained closed to them.
Davis had broken through that barrier.
Yet the military remained segregated.
Becoming a general did not make segregation disappear.
Instead, Davis would spend part of World War II confronting some of its consequences.
A General Confronts Discrimination
During World War II, Davis served with the Army’s Inspector General organization and undertook assignments involving the conditions and treatment of Black troops.
He traveled extensively, investigated problems affecting soldiers and units, and advised military leaders on matters involving Black servicemen.
His work took him overseas as well. In 1942, he was sent to the European Theater on special duty concerning issues affecting Black troops. He later served in Paris as special assistant to the commanding general of the Communications Zone.
His Distinguished Service Medal citation credited his investigations and advice with helping produce fairer solutions to problems involving soldiers and contributing to broader War Department policy.
Davis therefore occupied an unusual position.
He was simultaneously a senior officer in the United States Army and a Black American serving inside a military whose segregation policies continued to restrict people who looked like him.
Then Came His Son
There is another remarkable dimension to the Benjamin O. Davis story.
While Davis Sr. was breaking barriers within the Army, his son was preparing to break barriers in the air.
Benjamin O. Davis Jr. graduated from the United States Military Academy at West Point in 1936 after enduring years of racial isolation from fellow cadets. He would later become a military pilot and eventually command both the 99th Fighter Squadron and the 332nd Fighter Group, becoming one of the most important leaders associated with the Tuskegee Airmen.
For a period, father and son represented an extraordinary rarity within the U.S. military: two Black career officers operating at a time when opportunities for Black commissioned officers remained severely restricted.
Their stories would eventually become intertwined with one of the most important experiments in American military history.
The Tuskegee Airmen.
Fifty Years of Service
Benjamin O. Davis Sr. retired from active military service on July 14, 1948, completing approximately 50 years of service.
Less than two weeks later, on July 26, President Harry S. Truman issued Executive Order 9981, declaring a policy of equality of treatment and opportunity in the armed services regardless of race, color, religion or national origin.
The transformation of the military would take years.
But Davis had spent much of his career pushing against the barriers that made such a transformation necessary.
He died on November 26, 1970, and was buried at Arlington National Cemetery.
Among his decorations were the Distinguished Service Medal, Bronze Star Medal, France’s Croix de Guerre with Palm, and Liberia’s Order of the Star of Africa.
Why Benjamin O. Davis Sr. Matters
It would be easy to remember Benjamin O. Davis Sr. simply as the first Black general in American military history.
But his significance runs deeper.
He rose from private to general in an institution that placed substantial racial barriers in his path. He served with the Buffalo Soldiers, educated future officers, represented the United States overseas and advised military leaders about the treatment of Black troops during World War II.
And his story became the first chapter of an extraordinary father-and-son legacy.
Benjamin O. Davis Sr. broke one barrier.
His son would soon take the fight into the skies.
Next in our special series: The Tuskegee Airmen — The Red Tails Who Fought Two Wars.
Then, on the following Forgotten Genius Friday, we’ll tell the remarkable story of Benjamin O. Davis Jr.—from four years of isolation at West Point to commanding the Tuskegee Airmen and ultimately wearing four stars.
Forgotten Genius Fridays is an STM Daily News series highlighting innovators, pioneers and historical figures whose achievements deserve a larger place in our collective memory.
