... and then that magical moment arrives: the time-keeper is half-way through the launch count-down and every pilot has suddenly become as still as a statue. In less than five seconds, they'll all be launching tip to tip. One wrong move here or a slight shift in wind direction exactly on launch and the gliders might physically clash as they climb away vertically; potentially the whole group could tumble out of the sky. Even the wind often seems to hold its breath in anticipation.
