Yes it was the 'RAF one' I was flicking through and I am aware that "Inclusion of a site in this directory does not clear it for legal use by a commercial air ambulance operator."
As the thread was starting at the time, I was looking at the 3 clear route options of the various sites, purely out of interest as I'm sure that some must be used by 'commercial air ambulance operators'!
There doesn't appear to be many sites with that many options!!
Commercial air ambulance operators? in England? Bertie must be Scottish!
