Then you are off! To remind/inform you guys (depending on whether you are old or new), your ships are inside a giant elevator set into the mountain, which raises up to the exit hangar for take off and landings. The trick to such things- especially the landings- is keeping your ship steady as you fly through the resistance of the shield; if it cocks up your angle you're going to go into the mountain. This works well in your defensive favour as well though, so the moral is- amateurs should stay away from flying!
One by one you take off into the sky and set the co-ordinates for your journey...
