Right, I work with a bloke who has been a plane spotter for a long long time. He has just started a fotopic web site of all the planes he has managed to get good photos of (mainly private jets). I thought if there was anybody on here who shared the same interests, you may like to have a look at the web site for yourselfs. In a way I'm promoting his work just a tad! I'm not a plane spotter, but I enjoy seeing his work.
