The Landmark Milestone: U.S. Air Force’s B-21 Raider Stealth Bomber Begins Test Flights at Edwards Air Force Base
The U.S. Air Force’s B-21 Raider stealth bomber has commenced test flights, marking a pivotal step in its development.
Last Updated on March 4, 2025 by Daily News Staff

The U.S. Air Force’s much-anticipated B-21 Raider stealth bomber has achieved a significant milestone by commencing its test flights from Edwards Air Force Base in California. This development marks a crucial step forward in the evolution of this highly advanced aircraft, which took to the skies for the first time in November of the previous year.
An Air Force official, speaking to The War Zone, confirmed that the inaugural B-21, nicknamed Cerberus, conducted a sortie from Edwards, where it had arrived following its maiden flight from Northrop Grumman’s facilities at the Air Force’s Plant 42 in Palmdale, California. Despite the aircraft’s arrival at Edwards occurring without public fanfare, its significance is undeniable.
Flight testing, managed by the Air Force Test Center and 412th Test Wing’s B-21 Combined Test Force, aims to provide the U.S. and its allies with survivable, long-range, penetrating strike capabilities to deter aggression and strategic attacks. The Air Force has been notably tight-lipped about the B-21 activities, reflecting the highly sensitive nature of its development.
The 420th Flight Test Squadron, reactivated in 2019, serves as the centerpiece of the B-21 Combined Test Force, with Edwards having received substantial physical upgrades to support the test program. The base is expected to host all six pre-production B-21 jets in due course.
The B-21 Raider, set to replace the B-1B and B-2 bombers, is slated to enter service in the latter half of the decade. It will represent a central component of the U.S. military’s nuclear deterrent triad, while also providing crucial conventional long-range strike capabilities and intelligence gathering and battle management functions.
With Ellsworth Air Force Base, Whiteman Air Force Base, and Dyess Air Force Base all slated to receive Raider squadrons, the B-21’s role in bolstering the nation’s defense capabilities is already clearly outlined. As testing at Edwards progresses, the path towards operational service for the Raider is now well underway.
The B-21 Raider’s journey holds promise not only for the U.S. Air Force but also for the wider landscape of international security. As the aircraft’s capabilities unfold, it will undoubtedly shape the future of military aviation and strategic defense.

🌕 Blood Moon Over Arizona: Total Lunar Eclipse Visible in Phoenix on March 3, 2026
Last Updated on March 2, 2026 by Daily News Staff
Early risers in Arizona are in for a celestial show.
On Tuesday, March 3, 2026, a total lunar eclipse will be visible across much of North America — including Phoenixand the Valley. During this event, the Moon will pass completely into Earth’s shadow, turning a deep copper-red color often called a “Blood Moon.”
Here’s what you need to know.

🌍 What Is a Total Lunar Eclipse?
A total lunar eclipse happens when the Sun, Earth, and Moon align perfectly, with Earth positioned directly between the Sun and the Moon. As the Moon moves into Earth’s darkest shadow (the umbra), it doesn’t disappear — instead, it glows red.
That reddish color comes from sunlight filtering through Earth’s atmosphere — essentially, we’re seeing all the world’s sunrises and sunsets projected onto the Moon at once.
🕒 Phoenix Viewing Times (MST)
Arizona does not observe Daylight Saving Time in March, so these times are in Mountain Standard Time (MST).
- 1:44 a.m. – Penumbral eclipse begins (subtle dimming begins)
- 2:50 a.m. – Partial eclipse begins (Earth’s shadow becomes clearly visible)
- 4:04 a.m. – Totality begins 🌕
- 4:34 a.m. – Greatest eclipse
- 5:03 a.m. – Totality ends
- 6:18 a.m. – Partial eclipse ends
- 7:20 a.m. – Penumbral eclipse ends

The most dramatic portion — totality — lasts nearly one hour.
🌅 Where to Look in Phoenix
The eclipse happens in the pre-dawn hours, so the Moon will be low in the western sky as it sets.
For the best view:
- Find a location with a clear western horizon
- Avoid city light glare if possible
- Consider desert viewpoints, parks, or elevated areas around the Valley
Because the Moon will be setting as the Sun begins to rise, the backdrop of early morning twilight could make for stunning photography.
🔭 Do You Need Special Equipment?
No.
Unlike a solar eclipse, lunar eclipses are completely safe to view with the naked eye. However:
- Binoculars enhance color detail
- A small telescope reveals subtle shadow gradients
- A tripod and DSLR or smartphone with night mode can capture impressive images
🌎 Why This Eclipse Matters
This will be one of the most accessible celestial events of 2026 for Arizona residents. Total lunar eclipses don’t happen every year in the same location, and the timing — just before sunrise — adds dramatic visual contrast.
If skies are clear, Phoenix could have a spectacular view.
📌 Quick Viewing Reminder for Phoenix
Set your alarm for around 3:45 a.m.
Step outside by 4:00 a.m.
Look west
Watch the Moon turn red
No tickets. No crowds. Just the sky putting on a show.

Brightline West Nears Final Environmental Clearance Milestone
Brightline West’s final environmental assessment is 99% complete, clearing a major hurdle for the high-speed rail line connecting Southern California and Las Vegas.
Last Updated on March 1, 2026 by Daily News Staff
The long-awaited high-speed rail connection between Southern California and Las Vegas just hit a major milestone.
According to recent reports, the final environmental assessment for Brightline West is now 99% complete — signaling that one of the most critical regulatory hurdles for the project is nearly finished.
For a project that has been discussed for over a decade, this is significant progress.
What “99% Complete” Really Means
Before major infrastructure projects like high-speed rail can move into full construction, they must go through extensive federal environmental review under the National Environmental Policy Act (NEPA).
For Brightline West, this includes:
- Environmental impact evaluations
- Wildlife and habitat assessments
- Air quality studies
- Noise and vibration analysis
- Cultural and tribal consultations
- Traffic and community impact reviews
Reaching 99% completion means the overwhelming majority of those studies, revisions, and agency approvals are essentially done. In practical terms, the project is nearly clear of its final federal environmental review requirements.
That’s a huge step toward full-scale construction.
The Route: Southern California to Las Vegas
Brightline West will run approximately 218 miles largely within the median of Interstate 15, connecting:
- Las Vegas
- Apple Valley
- Hesperia
- Rancho Cucamonga (with connections to Metrolink toward Los Angeles)
Trains are designed to reach speeds up to 200 mph, cutting travel time between Southern California and Las Vegas to roughly 2 hours.
Instead of battling I-15 weekend traffic, travelers could board a train in Rancho Cucamonga and arrive on the Las Vegas Strip in about the time it currently takes just to get through the Cajon Pass on a busy Friday.
Construction Status
The project officially broke ground in 2024, and early work has included:
- Geotechnical testing
- Land surveying
- Utility relocation
- Pre-construction corridor preparation
While heavy civil construction has not yet fully ramped up across the entire route, completing environmental clearance removes one of the last major barriers before large-scale building accelerates.
Timeline Update
The original goal was to open before the 2028 Los Angeles Olympics. That timeline has shifted.
Current projections place passenger service around late 2029, depending on construction pace and financing milestones.
Why This Milestone Matters
High-speed rail projects in the United States often stall due to environmental review delays, funding gaps, or regulatory challenges.
Getting to 99% completion on final environmental assessment means:
- Federal review is nearly wrapped
- Legal vulnerability is reduced
- Major construction can proceed with more certainty
- Investor confidence improves
For Southern California and Nevada, it represents real forward momentum.
The Bigger Picture
Brightline West is privately developed, separate from California’s state high-speed rail system. If completed as planned, it would become one of the first true high-speed rail lines operating in the western United States.
The I-15 corridor between Los Angeles and Las Vegas is one of the most heavily traveled leisure routes in the country. A successful rail alternative could significantly reshape travel patterns between the two regions.
Final Take
The headline may sound small — “99% complete” — but in infrastructure terms, it’s a major breakthrough.
With environmental review nearly finished, Brightline West is closer than ever to turning renderings into reality.
Now the question shifts from if the train gets built… to how fast construction can move from here.

Aliens Visiting Earth? The Case for Studying UAP Like a Real Science Problem
Last Updated on February 28, 2026 by Daily News Staff
For decades, the idea of aliens visiting Earth has lived in a cultural no-man’s-land: too fascinating to ignore, too stigmatized to study seriously, and too easy to dismiss with a joke. But that posture has shifted in a measurable way over the past several years.
Physicist Kevin Knuth (University at Albany, SUNY) argued in a 2018 essay for The Conversation that the question of whether some UFO reports could represent something truly unknown is worthy of serious scientific study — not because we have proof of extraterrestrials, but because a small portion of cases appear to resist easy explanation and involve trained observers, multiple sensors, or unusual performance claims.
Article: https://theconversation.com/are-we-alone-the-question-is-worthy-of-serious-scientific-study-98843
That argument gained new oxygen in late 2017, when The New York Times reported that the U.S. Department of Defense had funded a program known as the Advanced Aerospace Threat Identification Program (AATIP). The reporting described roughly $22 million spent to examine military reports of unusual aerial incidents. Former Pentagon official Luis Elizondo became a central public figure in the story, saying he left his role amid frustration over secrecy and limited support for deeper investigation.
Around the same time, the Pentagon confirmed and released several now-famous military videos showing encounters recorded on forward-looking infrared (FLIR) systems from Navy aircraft — clips that reignited public debate and pushed the topic out of late-night-TV territory and into mainstream news.
What we’ve learned since (2018–2026)
The biggest “update” since your original post isn’t a single smoking gun. It’s the fact that the U.S. government and scientific institutions have increasingly treated the issue as a data and airspace-safety problem—and, potentially, a national security one.
A few key developments:
- The language changed: “UFO” has increasingly been replaced by UAP (Unidentified Anomalous Phenomena), a term meant to reduce stigma and widen the scope beyond “flying saucers.”
- Regular reporting became normalized: The Office of the Director of National Intelligence (ODNI) has issued public-facing UAP reporting in recent years, and the Department of Defense has continued formal tracking through dedicated offices.
- NASA stepped in: NASA convened an independent UAP study team, releasing a final report in 2023 that emphasized something simple but important: if you want answers, you need better data, consistent reporting standards, and transparent methods. (NASA’s stance was not “aliens confirmed,” but “this is a legitimate area for structured inquiry.”)
The Carl Sagan test still applies
Carl Sagan’s line remains the guardrail here:
“Extraordinary claims require extraordinary evidence.”
In other words: eyewitness testimony alone — even sincere testimony — isn’t enough. A personal story, a viral clip, or even a dramatic encounter doesn’t automatically equal proof of extraterrestrial visitation. If the claim is “non-human intelligence is visiting Earth,” the evidence has to be strong enough to survive serious scrutiny: repeatable analysis, multi-sensor confirmation, chain-of-custody, and independent review.
So where does that leave us?
If you strip away the hype, the most reasonable position in 2026 looks something like this:
- Something is being observed in a small percentage of cases that isn’t immediately identifiable.
- That does not automatically mean “aliens.”
- But it does mean the topic is no longer intellectually off-limits the way it once was.
After leaving AATIP-related work, Elizondo became associated with To The Stars Academy of Arts & Science, a group founded by musician Tom DeLonge that aimed to blend public interest, aerospace ideas, and advocacy for further investigation. Whether you view that effort as serious research, public outreach, or a media-adjacent project, it reflects the broader reality: the conversation has moved from fringe forums into public institutions.
The next step shouldn’t be louder claims. It should be better instrumentation, better reporting, and better science—because if there’s a prosaic explanation, rigorous study will reveal it. And if there’s something genuinely novel in the data, that’s exactly what science is for.
