Controller

Guide the planes to the runways by clicking and dragging. Occasionally, a departure will spawn next to a runway; click it to let it take off before the timer runs out and send it off-screen in the desired direction.

Emergency aircraft will occasionally want to land; get them to the runway with no delay!

Very rarely a white aircraft will bomb in, not talking to you, and just land on their own. You won't be able to control them, so get other aircraft out of their way!

Right click an aircraft to put it in a holding pattern if you need it to stay relatively put for a while.
