These vids are what i would miss if YT was torpedoed.
i make it a point to horde them all when i find them.
This video makes us appreciate how important computers today. Literally, every part of the engine was manually controlled by the users with their judgment, and most likely under some pressure too.
One take away is these aircraft reached the point where you couldn't 'just fly' them, too complex. Everything becomes about training, procedures, organization, and culture.
Technically B-25 is a war machine, not just to fly, but it is to destroy. It is the product of army with almost unlimited resources and manpower, at the end it is not about the UX or usability. They probably didn't even consider it for a second.
three main considerations for any mission:
seek opportunity, gain advantage, achieve objective.
the military "headset" is not the most familiar one to a lot of people, generally heuristics should be just as predictable as a machine. This is for example how it is possible to coordinate as a team and move while someone behind you is discharging thier weapon over your head, there is THE only procedure, not a selected procedure of equivalence. If you were to listen to radio transmissions when an aircraft went down, you should be able to predict what state the instruments and armaments of that aircraft will be found in, thus predict to i high degree what would be required for recovery operation, or if it is even worth risk of assets.
