As deplorable as the company-proposed response might have been, they will only have been providing what the customer required. If the customer only wants a big hook dangling under a Bell 47, and only offers enough money to pay for that, then a contractor wouldn't be either likely or able to provide an S-92 or EC225 with all the bells, whistles and SAR-experienced crews. The fault would lie particularly with those who decided on what was required in the first place...unless, of course, the Bell 47 was genuinely sufficient for the customer's requirement.
Besides, with an RAF SAR unit just down the road, why pay for an all-weather(ish), day & night capability?
