What happened
During the night, an aircraft was taken without authorization from its parking position on the apron at Valkenburg Air Force Base. The theft was carried out by two technicians who were under the influence of alcohol. After successfully starting the engine, the individuals managed to depart the airfield.
As the aircraft type (unspecified) began its initial climb, the flight became unstable and went out of control. The plane eventually impacted the sea in the vicinity of Katwijk. There were two fatalities among the occupants during the accident.
Findings
Investigations into the incident determined that the primary reason for the crash was pilot intoxication, which led to the loss of control during the early stages of flight.
