This plane was more or less an attempt at making a decently-handling (and good-looking) hypersonic jet, and also a testbed for selected-angle landing gear system I thought up. However, if you crunch the numbers, Kinematicist comes up a full mach short of the hypersonic barrier, but is still really fast.

Operation is as follows:
Takeoff at 25% throttle. Using any more could climb you out too fast, or even put you into a spin (If you blasted all engines at 100%). Once sufficient altitude is gained, pressing AG1 will engage the booster engines, propelling the plane within spitting distance of 3000 mph. Carefully trim your pitch as you accelerate, as the plane has very different pitching tendencies at different airspeeds. Note trim also pitches your ailerons as well to give the trim extra strength.

To land, first deactivate AG8, which will disable the middle landing gear, giving you a negative angle of attack on touchdown which will supply downforce to aid in your deceleration on the ground. Deactivate AG1 and throttle down to 5% for approach. Do circles to bleed away airspeed if necessary. At around 300 mph, lower landing gear, reduce throttle to 1% and begin you final approach. Once you are "over the fence", cut throttle, and carefully use active pitch control to set down the main wheels, then brake to drop the nose. If you came in too fast, AG2 will deploy parachutes.

EDIT: One of the ballasts in the nose is painted wrong. Take it apart to fix it, then nudge them back into place.
