I was never particularly bothered about planes until we moved to Stockport and found ourselves on the flight path...now I wouldn't exactly claim to be a plane spotter (not because I think that sort of thing is sad, far from it, just because I haven't got the encyclopaedic knowledge).. but I will happily while away a Sunday afternoon or summer Sunday evening in the back garden watching them coming in on their way to land, checking in on that FlightRadar app to identify them and see what's coming in next, even been known to get the binoculars out (hmm, so.maybe I am a plane spotter!). My favourite is definitely the A380, so graceful in its flight. It stops me in my tracks whenever I see it in fact.
My own personal daft ambition, not that I've done anything about it or am sure how I would, is I've always wanted to have a go at doing radio commentary on a game. Any game, any team, any station.
