Peep these two utterly ace wingsuit pilots, Reiner Ebert and Ludovic Woerth, hit more than 150mph as they step off a mountain and scream through the air above the Swiss Alps.

Ostensibly this video is a promo for Casio's new G-Shock GDF-100 and its in-watch altimeter and thermometer, but it also shows off some impressive high speed, high def footage from what looks to be a GoPro HD Hero. Either way, trust me: Turn on 1080p video for this one. Worth the wait.
