The command or facility to exit your plane depends on a couple of factors. If the arena is set to [b]not[/b] allow you to exit while the plane is in motion, you have to bail by either pressing the <ENTER> key 3 times, or typing ".eject" in the radio control message bar and pressing <ENTER>. If the arena allows you to exit while moving, the above will work, along with bringing up the clipboard and selecting, "End Flight".
