Planes spawn right above the airport

I think that for realism's sake, they should spawn off the screen and fly towards the airport, not spawn randomly on the page. Seeing a plane pop into existence breaks the immersion.

This should be fixed now.

It was caused because of this:

When the simulator/game starts, you don't want to have empty airspace above the airport, so I spawn a few planes with random offsets from 0.2-0.5 so some of them are visible; however, for some reason I set up the "recursive" timeout with the current offset.
