Sumburgh Airport
Dan-Air Flight 0034, a Hawker Siddeley 748 series 1 (registration G-BEKF) operating an oil industry support flight crashed on July 31, 1979 at Sumburgh Airport in the Shetland Islands. The aircraft failed to become airborne, ran through the perimeter fence, and crashed into the sea. The accident was due to the elevator gust lock having become re-engaged, preventing the aircraft from rotating into a flying attitude. The aircraft was destroyed and 17 of the 47 people on board drowned.
