The united nations have come together to spend two trillion to enlist 6 SR-74's The SR-74 goes mach 3+ and is more controllable than any plane that travels it's speed. There are two planes in 2018 that go faster than this, one uses the same ray technology as this and The A-270 starblast, the first spaceship plane with rocket controlled pitch and roll (i might make them after we get non-airbreathing engines that work over 100k ft. ) This plane is an intercepting fighter that has two heat seeking missiles and one radar guided missile. The maximum height is between 40k ft and 49k ft. it took some doing to make it this stable, also try taxing with this guy using yaw :) the engines have been upgraded using the latest technology so...
