IMHO the best replacement for the Puma/Wessex - type helicopter would have been/be the Westland Westminster. A twin jet Wessex with engines above the cockpit (NO CGB). It lifted the trailer plus a mounted Bloodhound missile together and that was back in the 50's. It was impressive but of course !!!!-canned by some short sighted tosser. It looked similar to the Blackhawk but had headroom enough to stand up inside.
