This North American XB-70A-1 Valkrie is the only injection molded kit in 1/72 scale of this experimental United States Air Force Mach 3 intercontinental jet bomber.  Only two copies of this experimental bomber were ever produced.  The second prototype was lost in a mid-air collision during a training flight which resulted in the first prototype being grounded and the concept of a Mach 3 intercontinental bomber abandoned.  The first prototype can be seen today at the United States Air Force Museum at Wright-Patterson Air Force base in Dayton, Ohio.  This kit is over 31" in length when completed and features the following: 1) A highly detailed cockpit and ejection escape system; 2) Landing gear and wheel wells and 3) Detailed YJ-93 Turbojet engines with afterburners.  The box is in investment quality condition.  Never started and factory sealed.
