I’ve been thinking about this since you asked. Let’s ignore how the plane got up there. That part is impossible. Let’s just say it is there.
I’m going to make a bold prediction: The plane will survive – but with shortened life.
Here’s why I think so.
When we run a durability test on a shaker we accelerate the testing by doubling the vibration level forces. Every doubling of the g levels shortens the testing one decade. For example a 2000 hour test can be shortened to 200 hours by doubling the g level. Double it again (4 times the nominal) and the test will be shortened to 20 hours.
Consider the pressure change of every flight, 1 atmosphere to 0.25 atmospheres, and back every take off and landing. Let’s say a plane has a life of 10000 TO&L. By doubling the pressure difference for each cycle: 1 atm to -0.5 atm (impossible) we will get a life of only 1000 TO&L. Since we can only go to 0 atm in space, the difference is an additional 33% so the durability test acceleration factor will be ~ 0.5 or about 5000 TO&L.
Yes. The plane and the people will survive – until they use up the oxygen on board.
If the craft is in orbit, would the passenger still collect their 25,000 frequent flier miles every 90 minute orbit?
