The SF Bay Area has 3 major airports - SFO, Oakland and San Jose with SFO being the most important. But back in 1927 Oakland had the longest runway in the world - over 7000'. It supported many pioneering trans pacific flights and even early radio navigation development. It was taken over by the Navy during WWII and the civilian traffic moved across the bay to SF, it never really came back.
Moreover, Oakland is setup more like 2 separate airfields, with the west side offering the long runway to jet airliners and the east being smaller jets and GA traffic. But that 'small' GA airport once had the longest runway in the world.

@USN_Submariner The LLNL door is trying to keep Neutrons in rather than blast waves out.
English
For comparison, the Cheyenne Mountain Complex in Colorado Springs' blast doors weigh just over half of that at a mere 23 tons

The massive vault door at Lawrence Livermore National Laboratory (LLNL) shielded the Rotating Target Neutron Source-II (RTNS-II). Just shy of 44 tons, 8 feet thick & 12 feet wide; it was the world's heaviest hinged door at the time.

They could actually take this up to Grizzly Creek Redwoods State Park and do this in the locations where they shot the chase sequence in RotJ

May the 4th Special: The Forest Moon Trauma. Our Scout Trooper test pilot contract says he has to stay at least 50 feet away from all redwood trees. We don’t talk about the last time...This one time he promised to make it through at least one forest without hitting a single tree.

I see the 2nd Stage getting integrated, I hope this means they're close to understanding and resolving the flight 3 issue.

New: When a mini-drone blew up in a Special Forces soldier’s face, a Army safety specialist wrote that in the Defense Department’s “rush to solve future and enduring threats related to [unmanned aerial systems], basic explosive safety principles are being ignored.” Army Special Operations Command pushed back saying it was his opinion and not based in fact. cbsnews.com/news/pentagon-…

My head canon is the Death Star weapon system was still in ‘Silicon Valley minimum viable product’ state - they could make it work for the investor demo but they literally had engineers hand tweaking things from the consoles in the depths of the machine to make it work.
jacob@jtimsuggs
The fact that there are no guardrails in this area because the Death Star was designed by Geonosians that could just fly away in case of an emergency is honestly such a great detail.

Right now, NASA's #MissionToPsyche is approaching Mars.
Current distance: 29,780 miles
Current speed relative to Mars: 10,340 mph
This simulated view, based on actual trajectory data, comes from our Eyes on the Solar System experience.

@Simberg_Space @TrevorScottReal It only seems that way to people who don’t understand California
English
@DJSnM @TrevorScottReal It seems a lot more like a Montana or Texas thing than a California thing. So out of character.
English
Can Texas officially legalize lane splitting please? 😅

POV: You’re coming home after a journey around the Moon. 🌕
Before reentering Earth’s atmosphere at the end of Artemis II, the Orion spacecraft’s crew module — carrying the astronauts — separated from the service module that provided propulsion and power throughout the mission.

@DJSnM Turbinia at the fleet review. Ckassic guerrilla marketing.

Victorian era steam turbine. Charles Parsons wanted to improve on the reciprocating steam engines driving electrical generation and came up with the Turbine. Then he demonstrated using turbines to power ships, this particular turbine came from the 4th ship to operate this way.
He took some of the money he earned from this technology and used it to buy the Grubb telescope company. His father had built the worlds largest telescope at Birr Castle in Ireland.

"Sound has always been important to me," said our founder, George Lucas, who celebrates his birthday today. "I'm a firm believer that it's 50% of the experience, and it's the neglected 50%. I've always made a practice of putting great deal of effort and creativity into my soundtracks, and hiring my sound editors before we start shooting the picture." That philosophy continues to inspire everything about our work here at Skywalker Sound. Happy Birthday, George, and thank you!

“For me, we were representing humanity going into space.”
The flags carried on the #Apollo9 mission were deliberate symbols of partnership and purpose.
From the US to the Netherlands to the United Nations, each one meant something. bit.ly/4dbxAiw

@ToughSf I did a video on scramjets In general a couple of months ago:

In 2004, NASA was flying the X-43A and broke the speed record for a jet aircraft by pushing its hydrogen-fuelled scramjet to Mach 9.6: youtu.be/25hqiWr8R-sThe next step was supposed to be a full-scale flying testbed with turbojet, ramjet and scramjet engines aboard.
