Thanks Frank....spot on. Imagine trying to get a cliff-sticker into a 3-point nappy harness!
Tec pilot - I take your point that we are in a new century but why change equipment that works well? If the strop is used properly you can't lose the casualty and, as Frank says, if there are injuries that prevent the use of the strop then we use a stretcher. We have been after a better system for lifting children for years but we still haven't lost any.
