My favourite book is "First Light" by Geoffrey Wellum - it is so well written that at one stage while reading it I had a mental picture of sitting behind him it his Spitfire cockpit when he was lost in cloud. I believe they are making a film of it to be shown in the summer.
Favourite DVD without any shadow of a doubt is "Night Bombers" a documentary about Hemsdale lancasters filmed in 1943 in colour by the station CO. The part where he is filming a lancaster struggling to take off while flying alongside it (in an Anson I believe) is just breath taking.
Favourite fiction movie is "Top Gun" ......... yes, I know, I'm sorry, really really sorry
