Originally, five Douglas DC-3s and one Douglas DC-2 airliner were available, but with the loss of a DC-3 on 20 September 1940 in a landing accident at Heston, and the destruction of another DC-3 in November 1940 by Luftwaffe bombing at Whitchurch, only four aircraft remained: DC-2 G-AGBH "Edelvalk" (ex-PH-ALE), DC-3 G-AGBD "Buizerd" (ex-PH-ARB), DC-3 G-AGBE "Zilverreiger" (ex-PH-ARZ), and DC-3 G-AGBB "Ibis" (ex-PH-ALI). In 1939, with war tensions in Europe increasing, KLM had painted their DC-2s and DC-3s bright orange to mark them clearly as civilian aircraft. BOAC repainted the aircraft in camouflage, with British civil markings and red/white/blue stripes like all BOAC aircraft, but without the Union Flag. They were later marked with their Dutch bird names under the cockpit windows. The interiors remained in KLM colours and markings.
