there are many other parts of the UK where the SAR crew are a fair distance away as well
Well maybe it's time to have a fresh look at UK SAR. We could start with a blank sheet, review basing, etc etc, and maybe integrate air ambulance operations as well. Almost like a harmonization of the SAR provision. All we need is a name for the project...
Doing this would remove the current arbitrary location of SAR bases. There might be scope to reduce cover at 3 flights to 12 hour ops. But surely noone would contemplate making two adjacent flights 12 hour ops
