Hi OddButAwesome,
I do see this problem. I know similar issues exist in Unreal Engine.
A hack/workaround to this could be adding a Mutator Zone with ‘Allow Jumping’ disabled. It looks like you can’t attach it to the airplane in the same way as you can with the Player Spawn, but you can animate the Mutator Zone in Sequencer.
I wonder using a prop mover device would solve this issue, I’m having trouble getting it to work. Also it looks like the ‘distance’ it can move is hard-capped to 400 meters…
