KSEA releases designs for their new aircraft, the X-9 SSTO Crew Vehicle!  The X-9 is the first aircraft to utilize the revolutionary R.A.P.I.E.R. engines, a dual mode engine that uses liquid fuel for atmospheric flight and can switch over to standard rocket fuel once the altitude makes the rocket mode more efficient.

Designed to succeed the current Crew Shuttles, this sleek jet has been designed to reach orbits up to 100k, dock, then return safely to Kerbin.

Production has already begun, and crews will begin testing soon!
