A couple of questions on the game engine mechanics ...

RE 2:

-No, aircraft that are intercepted or aborted due to Interceptors/SAMs do not suffer any ill effects but are merely "spent" and have to spend some time before they become available again (how much depends on the .pdt files).

Re 3:

-Yes, a unit that is wiped out is completely lost and will not reappear. Do not lose units, especially in the longer scenarios, since early losses will tend to "snowball".
