Summary: On May 15, 1972, Maj. Tom Pugh and Maj. Ronnie Rice flew an SR-71 (“Rapid Rabbit”) at Mach 3.2 when both generators failed, both engines flamed out, and the intercom died. Pugh restored power and relit the engines at Mach 1.1, but the damaged jet drifted over Hanoi at 41,000 feet; a later account explains why no one fired.
WHO: Maj. Tom Pugh; Maj. Ronnie Rice; the general who ran Hanoi's air defenses
WHAT: An SR-71 suffered generator and engine failures, then drifted over Hanoi; a later account explains why Hanoi's air defenses did not fire.
WHEN: May 15, 1972
WHERE: Hanoi, Vietnam
WHY: The later account attributes the lack of firing by Hanoi's air defenses to the circumstances described around the SR-71’s failure and recovery.
