This is the moment The Queen appeared to para-glide into the Olympic stadium from a helicopter, closely followed by James Bond actor Daniel Craig.
Where did the chimneys come from? Where did the parachutist who doubled for the Queen land? And how did so many Mary Poppins manage to fly?
It was a moment they and the rest of Britain will never forget. The young athletes describe what it was like to be part of history.
The Queen dropped in on the Olympic village today to wish good luck to Team GB athletes, who shared their experience on Twitter.
