In case anyone happened to be interested in this, I did actually figure something out. Using Menyoo, there is a Task Sequencer which (With a looootttt of patience) you can actually use to script an AI to walk to a plane, get in, and fly. I'm just having trouble getting them to stick to the taxiways and return to the runway.
I might post updates here as I figure them out, might upload the Menyoo world file if people are interested.

I think it would be really cool to see some custom scripted planes taking off and landing at the various airports, instead of appearing near the runway, and flying off in a straight line. It would be really cool to see a Jet land, taxi to a gate sit there for a few minutes, then taxi back out and take off, only to go and land at the northen airfield. I had a look, and couldnt find any mods like this, so i was wondering if anyone had attempted one.

So I have a bug that I cant trace the origins of, and I wanted to know if anyone has had a similar one. Whenever I go upside-down in a car, the rear end gets crushed in (even without hitting anything) and after that, I cant control the car in the air. If Im in a plane, the same thing happens, but I cant change the direction of the plane at all. It just freezes in that position, until it hits the ground.

@a63nt-5m1th You legend!!! Thanks mate, appreciate it!!

@MAFINS Angry planes don't do add-on ones though, and I don't always want to see a Concorde when it's coming straight for me

@SLY95ZER Heres a link to the vid:

@SLY95ZER There is a version of Angry planes that doesn't have a virus, I've got it. Just search it, there's a youtube video about it, and a link in the description.

Hey, I want to try and make some addon planes I have spawn in the air, and at the airport. Is this at all possible? And if so, does anyone know how?
