I think you're being rather unkind RTS.
I think survivors will be delighted to be offered a selection of hot and cold drinks and a bag of peanuts on the way up to the helicopter.
On a more serious note (if indeed the rumour is true), how do you mix crew-change shuttling and SAR standby in the same duty period?
Who is going to rescue the "shuttle" aircraft if it has a problem?
What happened to the concept of having a "dedicated" SAR aircraft offshore?
