The prototype Spitfire, K5054, in the vicinity of Eastleigh on May 1, 1936. Jeffrey Quill on this occasion was flying the Miles Hawk from which this photograph was taken. Mutt Summers was flying the Spitfire.

Another view of K5054 at the pre-Pageant show at Brooklands on June 30, 1936. Behind it are Supermarine Walrus I K5780, Vickers Wellesley prototype K7556 and Vickers B.9/32 prototype K4049, later to become the Wellington.

The Spitfire’s ability to survive forced landings was tested on March 22, 1937, when loss of oil pressure during high g turns and looping trials necessitated a belly-landing beside the Woodbridge-Bawdsey road. Damage was superficial.
