The photo below is from Jürg Läderach via Frank Schwarz. Jürg's father was pilot in the Swiss Airforce. He flew the Morane during WWII and after the war he became a testpilot. He went to the testpilot school in Boscombe Down in Britain, where this photo was taken. In the photo it's possible to see six Tempests. Anyone who can identify the persons?
Comment from Chris Thomas:
"I am positive the hangar in the background and large number of Tempests identifies the location as the Hawker factory/airfield at Langley. It is likely the ETPS students went there on a visit from Boscombe Down while on the course."
