6 Nov 86, Boeing Chinook helicopter crash; 43 oil workers lost #maritimehistory #OTD

On 6 November 1986, a Boeing 234LR Chinook helicopter returning workers from the Brent oilfield crashed on approach to land at Sumburgh Airport in the Shetland Islands.

 At 2.5 miles (4.0 km) from the runway the helicopter had a catastrophic forward transmission failure which de-synchronised the tandem rotors, causing the blades to collide. 

The helicopter crashed into the sea and sank. 43 passengers and two crew members were killed in the crash; one passenger and one crew member survived.
