What Goes Up Might Come Down features the high-flying humour of David Gunson. David is a Yorkshireman to the core - and proud of it. He was born in Sheffield (where, he insists, the M1 is cobbled!) and as a young man went to work in a steel foundry, but soon discovered that the opportunities for flying were far too limited. He left and joined the RAF, spending ten years in Coastal Command on Shackleton aircraft. He is thus well qualified to take us behind the scenes in the world of flying, and, with tongue very much in cheek, his 'after dinner talk' skillfully combines humour with hazard, raising many a laugh - and many an eyebrow. Dave Gunson's humour is based on fact, often mischievously, as with a wry smile he informs us that, "We force them down narrow corridors, thereby greatly increasing the risk of collision, while at the same time justifying the job of Air Traffic Controllers to keep them apart."
