On 8th Apr 1950 a version of the wartime Liberator bomber, the PB4Y-2 Privateer 59645 operated by VP-46 of the US Navy Detachment A, based at Port Lyautey in French Morocco, became the first casualty of the missions to probe the boundaries of the USSR. Commanded by Lt Jack Fette, the aircraft took off from Wiesbaden in West Germany and headed north towards the Baltic. The plan was for the aircraft to gather intelligence on Soviet naval activity along the Latvian coast.
