The second XB-45, 45-59480, over California on test from Muroc AFB during the summer of 1948. The B-45 was America’s first four-jet bomber to fly, the prototype making its first flight on March 17, 1947.
The XB-45 Tornado prototype pictured on take-off at Muroc AFB in February 1948. The large tailplane dihedral allowed adequate clearance for the efflux of the four 4,000 lb-thrust General Electric turbojets.
