Three B-52Bs of the 93rd Bomb Wing flew nonstop around the world. With the help of several in-flight refuelings, the bombers covered the 24,325-mile route in 45 hours and 19 minutes, cutting in half the previous record. Average speed was 530 mph.
From the Boeing web page to celebrate the 50th anniversary of the BUFF. I was stationed at Minot and accumulated 160 hours of BUFF time. Not bad for a non-rated staff officer who just liked to go flyin'!
