Shown here with the kind permission of the US Naval Historical Center this photograph shows some of the officers of the R34.
The caption reads "Officers who had crossed the Atlantic aboard the R-34, photographed following her arrival at Mineola, New York, on 7 July 1919. They are identified as (from left to right): Lieutenant Commander Zachary Lansdowne, USN, Observer; Lieutenant Wallace Durant, RAF, Wireless Officer (apparently wearing a U.S. Navy uniform); Lieutenant Guy N. Harris, RAF, Meteorlogical Officer; Major J.F.M. Pritchard, RAF; Brigadier General E.M. Maitland, CGM, DWO, British Air Ministry; Lieutenant H.F. Luck, RN, Second Officer; and Lieutanant J.D. Shotter, RN, Engineer Chief."
Sadly Major J F M Pritchard and Brigadier General Maitland were to lose their lives in the R38 airship crash in 1921 and Lieutenant Commander Zachary Landsdown was killed in the USS Shenandoah airship crash in Sept 1925.
