I doubt there is any sort of thing on the net which would be of the right format to import directly into your aircraft table.. it would require quite a bit of editing if it exists.
And it’s also likely that it would take more time removing aircraft you don’t want than it would doing a little research and entering the ones you do.. you might as well just wikipedia the planes you want.
However, a tool which can create an sql for the aircraft table based on your aircraft choices… it’s a good idea.
