I happened to mention this to a colleague today (an aerodynamicist) who reminded me of that little thing known as "ground effect". To fly a Tornado very fast whilst ground hugging, you literally have to hold it down to the ground i.e. push forwards on the stick... so it is unlikely the pilot was going more than 200-300mph (is that all!) when he hit the lamp, it isn't possible to go that low at any speed more than this. Dunno how high the lamp was, there are some in my town that are 50 feet or more (really!) so it could be that kind of height. Still pretty low, mind!
Cos sailors drink grog, arrrr!
Why if its call "sea-level", do all yachts sail at an angle?
