There is another S61 at Portland callsign " Whiskey Bravo", which has undergone maintenence,but will be made available in the morning. Portland is a meca for divers since the navy left, and the loss of the Coast Guard helo to Solent would not be too good for the poor divers suffering from the bends, which happens very frequently!
Big campagn on to stop the move from Portland to Solent for just this reason, 300 divers plus at the weekend!!
