I don't' see anything about airframe overstress in her question. What are you talking about?
The bit where he talked about airframe stresses in his post that you declined to read.
But no, I would not conduct mechanical stress tests of an airframe with a pilot and passengers on board.
But you would with astronauts and space suits. Nice double standard you have going there.
I don't think it would be important to the test to have dummies on board.
Except forensic aircrash researchers do. Have a nice documentary about it...
That's only a 3 minute summary, but I'm certain your uber research skills can find the full version.
When you fail to do so just ask and I will spoonfeed you the link.
But eventually, that plane is going to have to be flown by a test pilot to its specified parameters, probably beyond.
Why yes. Some crazy test pilot had to climb into the very first Boeing 747 which had never left the ground before and fly it for the very first time without knowing if it would work at all and also while having no effective means of bailing out and surviving if things went wrong.
In fact, go a little further back to the 707 and you find that test pilot Tex Johnson inverted a frakkin 707 to impress potential customers.
Only 1 min 44 of your time.
Those test pilots. They sure had balls of steel and took huge risks with untested equipment.
Oh, By the way, Aldrin, Armstrong and Collins were all test pilots.
I do think it important that astronauts wearing tested spacesuits with sublimators enter high vacuum on Earth prior to orbit for the last step of testing and training.
But you cannot say WHY you think that and you have been provided with ample reasons to NOT think that.
