The Great Mull Air Mystery From the May 1976 edition of Pilot magazine. A Cessna 150 took off from the unlit grass airfield of Glenforsa to fly a single night circuit, but vanished totally after completing the downwind leg. The mystery deepened later in 1976, when the body of the pilot, with no evidence of any physical injury, was discovered about half a mile away from the runway threshold. Update: I recently (09.06) came across more information on this here. Scroll down about half the page. Unfortunately this only serves to deepen the mystery...
