Boeing Names Independent Quality Review Leader

But this puts it in perspective:

We are already getting more information about the F-47's origins. Both Boeing and Lockheed Martin built an x-plane in their quest to win the manned tactical fighter component of the Next Generation Air Dominance initiative. As we already knew, a demonstrator first flew in 2019. Now we know another one took to the skies in 2022.

Air Force Chief of Staff Alvin put out a statement following the award to Boeing, saying that "For the past five years, the x-planes for this aircraft have been quietly laying the foundation for the F-47 — flying hundreds of hours, testing cutting-edge concepts, and proving that we can push the envelope of technology with confidence." At the time it was not clear that both of the finalists had flown demonstrator aircraft.

[...]

DARPA also states that both Boeing's and Lockheed Martin's x-planes flew "several hundred hours each" during the evaluation. It's unclear what the state of these aircraft are now. They could have served their finite purpose — not uncommon for flight demonstration vehicles with limited airframe hours designed into them — or they could continue to support NGAD and other programs, we just don't know. Boeing's aircraft could remain of particular value.



If it's been flying for 3-5 years, I'd imagine the bugs are probably worked out or on their way to resolution.
F-35's sure weren't. :)
 
These fifty year old Boeing 737-200s are remarkable in that they came with a gravel runway option.

Looking at how Boeing used to make aircraft with emphasis on safety and quality over profit, and assuming good maintenance I'd bet these are better than the new ones. I wonder what gravel capable aircraft are available to replace these -200s when they're finally used up? Some info on gravel kits here, including vortex dissipators, using compressor bleed air, in front of each engine.


Is there a spot on the pilot's logbook to indicate number of gravel landings?

B-727 was approved for gravel runways but they may not be able to find a museum that will sell their 727. Best solution is to buy L-188 Electras. Keep patching the wings and they'll fly forever.
