Will never forget mucking round on the beach at Newquay, Cornwall, as a kid, and hearing this distant rumble of thunder, with a clear blue sky, thinking wtf is that? And the rumble became a roar then a deafening explosion of sound as the one and only Red Arrows fly in formation about thirty feet above the cliff tops out over the sea, where they rehearse the next day's organised display. Seen them about 10 times now in various places. Always riveting to watch. They are simply the best, and probably the RAF's best recruitment tool.
