We stopped on a very high dune whilst driving in the Qatar desert. On top of a smaller dune on the other side of some water, we saw a black dot. We checked on this through binoculars and saw that it was a stuck vehicle (a Toyota FJ Cruiser) We managed to get around to it without driving through deep water.
It was on extremely soft sand, We winched it backwards to begin with, as the sand the Land Cruiser was parked on seemed firm.
This didn't really work. The FJ was out, but quickly got stuck again.
We repositioned the Land Cruiser and winched the FJ from the front (we should have done this in the beginning, (Hindsight)
In any event, it was out in just a few minutes.
