====Second prototype VX777====
The second prototype, VX777, first flew on 3 September 1953. More representative of production aircraft, it was lengthened to accommodate a longer nose undercarriage leg to increase the angle of attack of the wing, shortening the take-off run. It featured a visual bomb-aiming blister under the cabin and was fitted with Bristol Olympus 100 engines of {{convert|9750|lbf|kN|abbr=on}} thrust. At Falk's suggestion, a fighter-style control stick had replaced the control wheel. Like VX770, VX777 had the original wing with straight leading edges.<ref name="auto"/> VX777 was joined in formation by the first prototype VX770 and four Avro 707s at the 1953 Farnborough Air Show. During trials in July 1954, VX777 was substantially damaged in a heavy landing at Farnborough. It was repaired, fitted with Olympus 101 engines of {{convert|11000|lbf|kN|abbr=on}} thrust before resuming trials with Avro and the [[Aeroplane and Armament Experimental Establishment]] (A&AEE) at [[MOD Boscombe Down|Boscombe Down]].{{citation needed|date=November 2024}}
