No problem, all we have to do is drop our Crossfires from 3900 feet.
Airplanes are in the same situation when it comes to flying faster. A good rule of thumb is that if you want to fly twice as fast, then you will have to quadruple the horse power. So a Cessna 150 with a 100 hp engine can maybe do 100 mph while a typical late WWII fighter needed a good 1500 - 1600 hp engine to hit 400 mph.
