Salman, I am sure it was some way south R al K Int in the region of what is now Al Dhaid/Manama. There were no tarmac roads and very few settlements in those days. I can't remember how long it was before someone came across the wreckage as I was back in UK, but it must have been two years at least. The DC3 hit a low cliff on the eastern side of a dried up waddi and disintegrated into small pieces. Apparently the remains, covered in sand, were very hard to see. If there was gold on board it was never recovered!!
