Amazing sight lines for takeoffs and landings.

US Air Force Forgot How To Make Parts Of Its Own B2 Stealth Bomber And Now Wants To Reverse Engineer It
https://greatgameindia.com/air-force-reverse-engineer-b2-bomber/

What's the scoop here? The little old man that designed the heat exchanger on the B-2 passed and took all the secrets with him?
The specs got lost in a move?  The IBM PS/2 Model 57 SLC the files were on died and there were no backups?

The B-2 was designed on an early CAD/CAM system, certainly the first aircraft program I worked on where such a system was used.  Most of that early work was done at a now defunct Northrop facility in Pico Rivera, CA, then everything was moved to Plant 42 in Palmdale.   I know the plan was to destroy the jigs and tooling at the end of production, but I don't know if subsystems like heat exchangers were designed/built by Northrop or one of their subcontractors.  It's doubtful they were classified in and of themselves, but their end item usage and interfaces with the a/c probably were.

Poor guys never had a chance.

So the AC commander/instructor triggered the ejection during preflight and was the only survivor.  Not a good day for Russian military aviation on many levels.

An educated guess is the guy got one of the belts of his restraint system tangled in the seat initiation handle and tried to pull it loose.

Tragic. One would think there would be a switch housing that’s cover had to be raised manually to access the switch.  I believe that’s standard in Navy A/C as per NATOPS. I suppose if he was wrestling with his restraint system and exerted upward pressure to open the box and caught the toggle just right he could defeat that safeguard.

I’m basing the above on knowledge I picked up from sitting on a court martial board.  The same is true of fuel dump switches.

Nice little video here on the Martin Mars. Two of them are still being using to fight forest fires 70 years after being built.  Was just reading how they are having to limit the flight hours of the F-35 because they break so much.
