The AI jet, gunship, and cargo plane can't take off even when I drive them(in auto or off)
I would love to be able to make an automated airport(without cheating by removing this mod or getting Lex's aircraft)

I know this was fixed in previous versions so I figured you could do it again.

The AI planes from AAI aren't supported. Teaching the AI how to takeoff would likely require the AAI vehicles author to add that support.

As for crashes when using the non-AI planes, I opened issue with the AAI vehicles author
