Support craft, however, is clearly more of a detriment unless you are playing on a board with very little terrain. Being exposed to absolutely everyone from every angle makes them flying bulls-eyes.
Hmm, while in general airships were an accident waiting to happen during the early 20th century, it is notable that the Airships used over the US Easter seaboard in WWII as anti submarine patrols were very effective and quite difficult to shoot down. Perhaps you could increase the DC to reflect this, offsetting the disadvantage of being a 'flying bullseye'.
OTOH the Squats probably don't care too much about such minor details as survival, just as long as it crashes on top of an enemy formation - so perhaps the notes could reflect that by having the pilot try to steer the dying craft onto an enemy formation within "X" cm (is 20 cm too large?). Move to intended location, scatter with 2xD6 and dice for all affected units that are in contact.
And I suggest this should always happen unless
a Critical is scored, blowing the thing out of the sky . . . .
