HH, as a plan I would agree but in reality, where the guys on the ground are danger close the airman has frequently stood in to danger even at risk to themselves.
Nick Richardson in 1994 is a British case in point. Then in AFG there are plenty of instances with Apache and Chinook both standing in to danger when prudence would suggest otherwise.
Plan for the worst and hope for the best. Planning a 'soft' coin ac expecting to lose some is not planning for the worst.
