I managed to get the normal plane to go 4000+ km/hr

I flew straight up into the air until 100,000+ ft trying to reach mars, decided to turn back and throttle straight down. From this I managed to get under the map but popped back up, and then noticed i was going 3,000_ km/hr. I then throttled until 4000+ and got a crazy Star-Wars hyperdrive whatever its called animation. Pretty cool.
