Just a question here; are the UK military now flying single front seat occupant flights on NVG? And what about the normal crew complement of an Air Ambulance heli? BTW, possibly the most dangerous thing to do on NVGs is to try to use them to push the "visual" night weather limits.
Back to the core subject, for those seemingly to consider this as only a matter of the experience and competence of the pilot up front. Make no mistake, it most certainly DOES need to be matched by that of both the winch op and the person going on the wire. Especially so if the person to be winched up is on a stretcher.
