Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. The Sumburgh disaster was the crash of a Boeing 234LR Chinook helicopter on 6 November 1986 with a loss of 43 passengers and two crew members. The helicopter was on approach to land at Sumburgh Airport Shetland Islands returning workers for the Brent oilfield. At 2.5 miles (4.0 km) from the runway the helicopter had a catastrophic forward transmission failure which de-synchronised the twin rotors causing the blades to collide. The helicopter crashed into the sea and sank. The helicopter was normally based at Aberdeen Airport but had been based at Sumburgh Airport since 3 November 1986 to operate a shuttle service from the Brent oilfield in the East Shetland Basin. On 6 November the first flight was delayed due to an oil leak from an engine gearbox but was soon rectified and the aircraft left Sumburgh at 08:58 with 40 passengers for the Brent Field.
