The Kvitbjørn disaster occurred on 28 August 1947 when, in heavy fog, the Norwegian Air Lines Short Sandringham flying boat Kvitbjørn, registered LN-IAV, hit the monutain Kvammetinden about north of the village of Lødingen in Lødingen Municipality in Nordland county, Norway.[1]
The flying boat crashed en route from Harstad to Bodø, the two stopovers between its origin Tromsø Airport and destination Oslo. All thirty-five people on board (twenty-eight passengers and a crew of seven) perished, making the crash the deadliest in Norwegian aviation at that time.
