@ Mudpuddle: It does look like something of the kind doesn't it! [lol]
@ Stephen: Oh, it's MASSIVE isn't it. Not exactly very stealthy (or fuel efficient no doubt). The North American Aviation XB-70 Valkyrie was the prototype version of the planned B-70 nuclear-armed, deep-penetration strategic bomber for the United States Air Force Strategic Air Command.
They only ever built 2 at a unit cost (in the late 1960's) of $750M. That's $5.2 *Billion* in today's prices!!!
