It so happens that in the last few days I have listened to several presentations about HHO, listened to several winchmen's stories about close calls with single rescue strops, and had a discussion with a representative of a regulator about this subject.
When people started doing this in the 1950s, rescued persons were often fit young airmen who had just banged out of rather unreliable fast jets. There was a military front-line risk profile and we didn't know the half of what we know now about either the physiology of rescue strops or the usefulness of helicopter rescue. It is time for all the users of rescue strops to take a good look at the way they operate and adapt to 21st Century reality.
EDIT
Emergco Evac? How much has to go wrong for that to fail?
