Again, slight tangential.
In the old DEW Line days the DEW Sites were in remote and inhospitable places. At Goose there was a 'cowboy' flying for Ogginawa (sic) helicopters. I believe he had some battered old Sikorsky IIRC. He had the contract to fly to the sites and said because the conditions were too bad for the regular military types.
So contractors can, and do, do things that the military cannot.
