Bag Man,
Chappie in question got a DSC (other crew also decorated) and is, I think, still serving. As for getting lost, there is some evidence (in public domain through ex-SF guys' memoirs) that suggests it was not the pilot who got lost but the SAS troop commander, who insisted that the pilot was lost when, in fact, he put the helo down in the right place. Despite best efforts of pilot and crew to convince otherwise, troop cdr insisted on continuing and landing miles from the right place, completely scuppering any chance of successful mission (another view is that he gave up when a bit of hard marching could have put things back on track - but that may be unfair). Trp Cdr's career did not progress much further....
