One "what if" scenario that has always interested me is what could the Belfast have done as regards the build up to the Argie invasion of the Falklands in 1982 in reinforcing the islands before the Argies came ashore on 02 Apr had the aircraft not been removed from RAF service in 1976 and the US allowed operations from Wideawake.
Was the AAR system in the aircraft usable?
Could the aircraft do para drop or do LAPES to get some form of heavy weight weapons down there? I assume that the runway at Stanley would have been too short to do a landing and take off.
Of course the Belfast was invovled in moving stuff to Wideawake from the UK in the colours of Heavylift.
