Only the aircraft of the Royal Norwegian Navy Air Service (one M.F.11 and four He 115s) had the range to fly all the way from their last bases in northern Norway to the UK. Two Army Air Service Fokker C.V.Ds and one Tiger Moth also managed to escape eastwards to Finland before the surrender. Further three naval M.F.11s and one He 115 flew to Finland, landing on Lake Salmijärvi in Petsamo.[25] All the former Norwegian aircraft were later flown by the Finns against the Soviet Union.
