On 18 July 1944, a British Corsair F4U-1A, "JT404" of 1841 Naval Air Squadron, was involved in anti-submarine patrol from HMS "Formidable" en route to Scapa Flow after the Operation Mascot attack on the German battleship "Tirpitz". It flew in company with a Fairey Barracuda. Due to technical problems the Corsair made an emergency landing in a field on Hamarøy north of Bodø, Norway. The pilot, Lt Mattholie, was taken prisoner and the aircraft captured undamaged. Luftwaffe interrogators failed to get the pilot to explain how to fold the wings so as to transport the aircraft to Narvik. The Corsair was ferried by boat for further investigation. Later the Corsair was taken to Germany and listed as one of the captured enemy aircraft ("Beuteflugzeug") based at "Erprobungsstelle Rechlin", the central German military aviation test facility and the equivalent of the Royal Aircraft Establishment, for 1944 under repair. This was probably the only Corsair captured by the Germans.
