everyone keeps talking about the noise, but in many ways more impressive was the quietness with which they could fly
As a kid I lived near Yeovil, and the Vulcans were often see on low-level flight profiles in the area, presumably dummy attacks on Yeovilton / Westlands and other strategic targets
It was quite common to be able to look down on them from Ham Hill, and see them quietly gliding along. Often the only sound was in passing, as you experienced a "hum" something like the blue note of the Hawker Hunter, presumably caused by aerodynamics. One unforgettable sight was when one popped up around 100 feet over my head as it traversed a ridge-line road leading up to the hilltop, before dropping down again on the other side, down the next valley with me looking down on it. Sounds simple until you realise the valley was only around 150 metres wide, with a depth of 50 metres - and I was looking down on it from behind. The Vulcan wingspan was around 34 metres, the height just over 8 metres .Not a lot of room. And it was totally quiet. How the heck a pilot could keep a thing like that in the air, for so long, at low level is amazing
