As I see it the RAF SAR bases have to do some clever/flexible crew rostering and the 'liberated' front end crews will probably be converted to the Chinook and sent to Afganistan to relieve the present crews.
What is happening to the RN SAR crews, shouldn't they be scheduled in a similar manner to fly the RM around or dare I say the Army?
As a civilian I have little knowledge of the air operations out there but it is obvious that every service is overstretched.
