"If Boulmer is going to be day only,are they thinking about trying to cover some of the east coast from Glasgow?"
Why not? Each unit cover jobs in the others "area" anyway. so why would it be any different - if the ARCC need some one they will surely task the nearest suitable asset. Prestwick have already been on the east coast and infact just off Boulmer in the past. Likewise Boulmer come over to the west coast if Prestwick are out of area.
" is the new SAR cab going to scramble from Glasgow (in $hitty Weather - and fly under the Bridge) to go and transfer her to a hospital. At the moment the answer is yes. What will be the answer in 3 years time? "
Why not (again)? why fly under the bridge when the S92 could climb out IFR then let down over the water?
