Helicopter rescue feasibility
Watching the awful events at the tower block in London got me thinking. Could there not be a capability for helicopter based rescue in such circumstances?
Coast Guard (and previously RAF/FAA SAR) operate winch equipped helicopters that are designed with equipment to lift people and casualties.
I was wondering if this was something that was ever trained for, or are the winches capable of operating this close to a structure?
Or was it never considered a useful capability, considering the rarity of this type of tragedy?
Do other countries/services have this sort of capability?
