This morning I was pootling along at around 30mph when all of a sudden there was a horrible graunching noise (as it seemed to me) from behind. Thinking that something had failed at the back of the car I was all set to pull over when, in my peripheral vision, I saw an Apache helicopter cruising about 150 ft over me, going just 10 or 15 mph faster... ugly, noisy beggars! We often see them go over, but usually a fair bit higher - where I live, they use the traffic on the A12 for sighting practice, according to someone who worked on the base.

This one was very low and, in the direction he was heading, he couldn't avoid going over a large village - very naughty, as they're not supposed to fly so low over populated areas.

Got some compensation later though - a spitfire came over my house this afternoon, but at a legal height.

150 ft that's pretty high, I had one come over the top of the boat we were on about 5 years ago when we were cruising the Norfolk Broads. I reckon he was no higher than 20ft and the down draft was enough to rock the boat.

Many years ago I was driving down near the bottom of a valley in North Wales when I was overtaken by an A10 at the same altitude as me... but that's another story!
