A quick review of the "facts":
1) SAR-H no longer encompasses the Falklands, meaning:
2) the next FI ac has to be drawn from the military
3) Chinook and Merlin are committed to war roles
4) Puma has no dedicated role (or am I missing something?)
5) The RAF SAR Sea King force has had 30 years of continuous ops and has never been granted a rest.
