QDM3, yes it was Hayle as I recall, although there were a couple of other options at first. As it was intended to be a fly-in by several aircraft there was a (local authority?) requirement to provide marshals for public safety - which seemed reasonable. Also the marshals would have been able to check out the surface conditions 'on the day'. But, sadly, it blew, and it p...ersisted down.....
