Yeah, I think that's where I heard about it first as I've always had an interest in aviation. I think it runs in my blood (I use to fly paragliders) as I have a cousin who use to fly the harriers in the royal navy, an uncle (on same side of family as my cousin) who retired as a Sqn. Ldr from RAF Coningsby and his brother who's been an air traffic controller all his career.

Many thanks,
Rob.
