The PH-AEH of KLM at Eindhoven-Welschap airport. In 1929 the engines of the PH-AEH were mounted in the leading edge of the wing. It received the designation F.VIIIa As this aircraft was also used for aerial photography and mapping, this configuration made it easier to photograph from the (open) cabin windows. KLM's PH-AEH was sold in 1936 as PH-OTO ( "PHOTO") to the RSL, (Government Service for Aeronautical Studies ). In September 1939 PH-OTO was leased to the LVA. (The Aviation Department of the Royal Netherlands Army). (Beeldbank RCE, photo SP-0018)
