Hang on Crab,
Couple of issues with what you've asserted there.
How will civ flights manage serviceability with 2-300 jobs a year? Well given half are S92 flights and since that types introduction in 2007 the average rate was above 98%, which no mil SAR flight was managing despite often there being more than one spare airframe per asset. Civ SAR managed with only a single spare per base and will continue to do so, also only 2 engineers per duty, the norm for many many years.
UKSAR was definitely compromised in the latter years, flights having only a single rear crew member on board and unavailable for winching due to staff shortage to support the front line. Yes, it happened.
Not having a go, you raise many valid points but those mentioned required clarification.
