X-313 "SpeedDemon" - The Kerbal Griller

This is /L Aerospace proposal for the X-313 Experimental Hypersonic Jet Program.

Nimble, relatively cheap, fast.

But tricky to take off and land - keep the wheels heavily loaded (full ailerons up) while rolling for taking off, or she will kick you off the runway.

(And remember to start the Fuel Cell. the RAPIER doesn't generate EC!)
