When I were a lad I was sitting on the beach at Bridlington when everybody looked up as this Vulcan passed overhead at rooftop height, possibly coming down a little now it had cleared the buildings. It was so unbelievably low I could read the smaller stencilling under the wings.
It roared out to sea just feet over the waves. Everyone within earshot was saying how amazing that had been.
That was probably the most impressive thing I've ever seen, and I would love to see one of those fly by again.
That said. It would be a shame not to keep a few Concordes in flying condition, to drag out on special occasions. The most beautiful plane in the known sky.
