All six crew and 26 passengers on board a Dutch Dakota Association Douglas DC-3 (PH-DDA) were killed when the aircraft crashed into the Wadden Sea just north of the Netherlands. The aircraft was on the return leg of a 25 September pleasure flight from Amsterdam Schiphol Airport to Texel Island when the pilot radioed that there was an engine problem and that he intended to divert to the nearby De Kooi air force base. The Royal Netherlands Navy found the aircraft wreckage on a sandbank in the Wadden Sea off Den Helder, Netherlands.
