As part of the USAF's evaluation process, all five aircraft were submitted to a series of fly-offs to determine their performance. On 21 February 1951, a British Canberra B.2 (WD932), flown by Roland Beamont, made the transatlantic journey, arriving in the United States to participate in the competition; by making this journey, the Canberra thus became the first jet aircraft to perform a non-stop unrefueled flight across the Atlantic Ocean, travelling from Warton, England, to Gander, Newfoundland and Labrador, Canada, in the record time of 4 hours 37 minutes. On 26 February 1951, the flyoff took place at Andrews Field, Prince George's County, Maryland; each aircraft was tasked with performing a set sequence of maneuvers within a ten-minute window, directly demonstrating its agility and performance against its rivals. According to Gunston and Gilchrist, the Canberra proved to be significantly superior to any of the competing aircraft, and its selection was beyond doubt by the end of the competition.
