Alex Duncan was one of the best wingsuit jumpers in the sport. When asked about the dangers of wingsuit flying, this is what he said. "You have to have a mix of a little bit crazy and a little bit brave, but you have to be sensible too. You need to have a good balance where you don't let fear overcome you." Mr Duncan began skydiving when he was 19. After a few years, he started BASE-jumping and later tried out wingsuiting in Europe. He was killed on last week after crashing into a mountainside during a jump in the Swiss Alps. Alex Duncan died doing what he loved.
