"At that time (1909) the chief engineer was almost always the chief test pilot as well. That had the fortunate result of eliminating poor engineering early in aviation" (Igor Sikorsky).

About 18 months after XB-1's last test flight, the team is back in a control room getting ready for our next big test event.
They're all pretty happy it's *not* in the Mojave desert this time.

59 Seconds on NASA's X-59 : Envelope Expansion ✈️
NASA's X-59 test pilot Nils Larson shares a behind-the-scenes look at what it takes to fly the one-of-a-kind X-plane.
In this video, Larson explains the envelope expansion phase of the X-59 program. Envelope expansion is a series of flights at different altitudes and speeds in which the team performs tests and collects data to demonstrate that the aircraft can safely operate in national airspace.
As testing continues, NASA is flying the X-59 higher and faster and will ultimately evaluate its quiet supersonic performance.

Tomorrow, @NASA will announce the Artemis III crew astronauts who will fly aboard the @lockheedmartin-built Orion spacecraft and test critical rendezvous, proximity operations and docking capabilities needed for future lunar surface missions.

Don't they know they aren't allowed to create sonicbooms unless authorized by the FAA

Symphony high pressure turbine disc assembly started this morning. The blades are expected on dock this week and will start going on the disc soon.

Supersonic. Mach 1.21.
Quarterhorse Mk 2.1 is now the world’s first privately developed, unmanned supersonic jet and the fastest unmanned aircraft flying today.
This flight makes Hermeus the fastest company in aviation history to go from founding to supersonic flight - exactly 364 days after the maiden flight of our first aircraft.
Now, we fly faster.
A special thanks to @DIU_x, Director @OwenWest91, Maj. Gen. Joe "Solo" Kunkel, and Deputy Director Kyle Norman.

This is one of the more insightful things I've read this week:
"By the late 1930s [the Germans] had developed the weapons that would in the main be used to fight the Second World War.....When the war came they tried to speed the process of development up, to win the war with the weapons of the 1950s. The result was a technical disaster: shortages of resources, constant political interference, the inherent difficulty of accelerating research work at the forefront of science, all meant that German forces got little in terms of performance from the new weapons to match the great expense of producing them. The Allies...stuck with the weapons of the late 1930s, and pushed them successfully to their limits, in most cases overtaking the performance of Germany's most conventional weaponry. When after the war they came to develop missiles, jets, advanced submarine technology, and a host of other vanguard equipment, they simply took German scientists and blueprints."

I believe Paul can explain what's going on here, in Romans 1 for example.
Psalm 19 does a fair job as well.
NEW: Artemis II Commander Reid Wiseman reflects on being MOVED to tears by the Christian cross after returning to Earth from the historic expedition:
"When I got back on the on the ship — I'm not really a religious person — but there was just no other avenue for me to explain anything or to experience anything."
"So I asked for the chaplain on the Navy ship to just come visit us for a minute, and when that man walked in, I'd never met him before in my life. But I saw the cross on his collar, and I just broke down in tears."
"It's very hard to fully grasp what we just went through."

Raising the gear for the first time is a big deal in flight test
Wheels up for NASA’s X-59. ✈️
In its first wheels-up flight, the aircraft revealed its sleek, streamlined design—key to reducing sonic booms to a quiet thump.
See how this milestone moves us closer to quiet supersonic flight over land:
