1. Pilots of No. 32 Squadron. This photo was taken by Ministry of Information photographer David McLellan and can be found at the Imperial War Museum in London (catalogue number Q 12041). The IWM description reads: “Pilots of No. 32 Squadron. An American, Canadian, New Zealander, Englishman and South African, respectively; Green, Lawson, Leese, McBean, Hooper. Humieres aerodrome, near St. Pol, 15 May 1918.” I believe the identification of the men, left to right, is correct, although the nationalities have been incorrectly assigned. Humières was about a mile northwest of Beauvois. Parr’s nose looks slightly crooked. Perhaps the effects of the crash mentioned in his letter of February 18, 1918, are visible here (although not in other post-crash photos).
