Prator: In the event of an emergency, all of the security doors are designed to shut and lock immediately to quarantine the area in which the emergency is happening. People who get trapped inside are irrelevant.
Most of the time, you don't get any air support. You might fly around in a dropship large enough to carry a tank, but tactical airstrikes just ain't gonna happen... unless they're targeted at you.

Some games if you survive long enough you lose in a cut scene instead and get a special item and tons of xp. Xenosaga, FF8, Tales of symphonia, Tales of Legendia, etc..
In FF5 it is possible to kill the final boss in his first form only. The game pauses a bit the resumes with the ending.
