Why would anyone need a 65-foot tall diving platform? The Montreal Olympic Sports Centre has a 20-meter diving board, to go along with their many other specialized swimming and diving facilities. It was cliff diver Lysanne Richard who talked them into adding the super-high platform. After all, they had room for it, and it's indoors where she can practice out of the cold. Tom Scott climbs up to the platform, but it's Richard who takes the plunge -after she sends her shoes down by zipline.
