This aircraft is an All In One Jet, (Alles In Einem meaning all in one in german) this aircraft has a few extra abilities on top of flying.

It has two engines that should be run once at a time, 1 being the takeoff engine and getting up to speed at 100% but once you turn 1 off, turn engine power to 5% and switch to engine 2. You should instantly gain a ton of speed. But if you want to slow down, turn engine 2 off and turn engine 1 back on to 100%., you can switch inbetween the engines, 1 for lower speed bombing fighting and 2 as mainly just transport at hyper speed basicly, you can turn engine 2 up all the way but i reccomend a gain in altitude where there is way less air. 3 is instant stopping parachutes and 4-5 are bombs, its pretty well armed, and when airbrakes activiate it will slow you instatly to almost landing speed and if that doesnt do the trick, activate the chute! :D have dun and do what you want with it
