In Feb '47, a P-82 with the name “Betty Jo” completed the longest nonstop flight by a fighter aircraft without aerial refueling by flying from Oahu to New York. This flight still stands in the record books today, some 78 years later, one of the biggest achievements for a piston engine fighter.

 The North American P-82 Twin Mustang had been designed for the express purpose of being a long-range escort fighter, meant to accompany Boeing B-29 Superfortresses on bombing raids from the Mariana Islands to the Japanese Home Islands and back, with one pilot each in the P-82’s two fuselages to fly the aircraft in shifts in order to combat fatigue.

 But while the XP-82 Twin Mustang would make its first flight on June 15, 1945, WWII ended before it could conduct it’s combat trials.
