Hardly a good comparison. This was an offshore machine with no rear crew.
I suggest you have a good rethink, how does the lack of a rear crew give absolution. The only time I've needed a rear crew was for firing the guns and winching. Didn't even have them for sling loading. Mind you they were helpful giving clearances into tight holes for medevacs when trimming the shrubbery with main rotor was a necessity.
