From the Wikipedia article

The Airship NS11 crash was an airship accident which occurred on 15 July 1919. The Royal Air Force (RAF) airship exploded off the east coast of England over the North Sea, killing all nine crew on board.

Accident

NS11 had taken off from RAF Pulham in Pulham St Mary, Norfolk, around midnight on the night of 14/15 July 1919 and was heading over the North Sea on a mine-hunting patrol. In the early hours of 15 July, she was seen to fly beneath a long "greasy black cloud" off the village of Cley next the Sea on the Norfolk coast when locals reported an abnormal noise from her engines (which may have suggested she was experiencing engine trouble). She was returning towards the coast when she exploded into a ball of flames, causing a vivid glare lasting for several minutes as the burning airship descended, plunging into the sea after a second explosion. None of the nine crew members on board the airship survived. The Sheringham lifeboat was launched but its crew could only find a small part of the aluminium wreckage.

The accident occurred less than 48 hours after the airship R34 arrived at RAF Pulham after a successful double-crossing of the Atlantic Ocean, including the first-ever east–west crossing by air.

Investigation and cause

Cause

The findings of the official Court of Enquiry were inconclusive, but amongst other possibilities it was thought that a lightning strike may have caused the explosion.
