TAKE CARE WHEN CROSSING ROAD - cars can drive fast around the nearby corner.
Also note that there is a Police checkpoint at Birakt al Mawz at the bottom of the mountain. They want to check you license; car insurance and that you have a 4x4. They will NOT let you up is this is not in order.

Basically in the 1950's, Oman was at war with itself. The coastal areas under the Sultan and the inland areas (under a local Imam) were fighting..
The Sultan asked the British to assist. They provided both ground and air support. The full story can be obtained from the above link - with some great photos and personal experience)..
This Venom fighter crashed while Flight Lieutenant Owen Watkinson was on a sortie out of Sharjah. The small cairn/tomb next to the cache is his grave..

The wreckage still left is part of the central structure (the base of the 2 wings) and cental turbine housing..

Unfortunately many of these have been removed - I am not sure why. But I leave them in the hope that they return. The tops ones seem inactive. Also watch the Jason Stratham/Robert De Niro move "Killer Elite (2011)" for a Hollywood take on a Sir Ranulph Fiennes book on the aftermathy of the Oman conflict.
