Found this amazing image of a Valkyrie today..
The design is amazing, the fuselage in an airfoil configuration.
thought I would share
EDIT:
American XB-70A Valkyrie. The Valkyrie measured 185 feet in length, had a wingspan of 105 feet and an empty weight of 210,000 pounds. With a GTOW of 550,000 pounds, it was the heaviest supersonic-capable aircraft of all-time. The aircraft was powered by a six-pack of General Electric YJ93-GE-3 turbojets totaling 172,200 pounds of thrust in afterburner.
Just found this on Pinterest, some really amazing aircraft photography can be found there...
