How often do units actually get hit when an aerospace unit crashes? I'm betting for fighters it's pretty rare, but more frequent with the area damage caused by DropShips. At least units at hex 0909 are immune to crashes from aerospace units on the same map!
Do units often survive crashes or being hit by crashes? It's probably safe to assume that it depends on the damage done and the unit.
It says that the damage to buildings and units equals the damage to an aerospace unit, but it also says units take double damage when crashing into a hardened building. I'm assuming that this double damage only applies to the aerospace unit, not to the units hit.
Speaking of damage, do units ever survive the re-entry damage? I'm not sure how much damage DropShips can take, but 250 per velocity seems like it'll destroy anything.
Maybe this should be in the aerospace section, but it also applies to the ground combat...
