As the posters above have said it's called "Sole Survivor". Made for TV movie back in the early seventies. Story is based on the wreck of an aircraft found in the Libyan desert by chaps prospecting for Shell Oil.
I was searching for it for ages - found it on eBay a couple of months ago.
Good movie
Can burn you a copy off if required - it's not an original as it was never released on video or dvd etc.
