Sandro Dias is a 50-year-old Brazilian skateboarding legend; he's a six-time vert world champion. Well, he recently made history once again when he dropped in from the curved facade of a 22-story building in Brazil. 

Until now, the Centro Administrativo Fernando Ferrari (CAFF) building in Porto Alegre, standing 88.91 meters high, has been a white whale in the skateboarding community, which has dubbed the unique structure the "ultimate skate ramp." — Dias himself says he has dreamed of riding CAFF for some 13 years.
