Vfr I understand your tack. This Corporate body thing always changes with the wind. For what it is worth [probably very little] the Corporate body has convinced its coal face workers that the NAAAS thing is worth supporting into the future.
Whether that decision will survive any financial problems that always hit such organisations from time to time [and I have no insider line here] remains to be seen.
The fact that most EMS heicopters are whizzing around with AA badges on does tend to provide a pretty good image for 'the fourth emergency service' as the AA like to see themselves and is probably far cheaper than advertising on TV or in the glossy magazines.
Perhaps you have to be horizontal on a stretcher to apreciate who sponsors the UK EMS!
The number of AA adverts on the box must be very low or maybe I am stuck on the BBC! Overall I reckon that even if they do not extend the scheme [and the Ulster requirement must be pretty urgent now as the Wessex h/c of 72 Squadron are due to pull out of the increasingly unsettled province in December] they are getting pretty good value.
