Speedflying is an intense sport. It’s not BASE jumping. It’s not wingsuiting. The speedflying wing is much smaller than a paragliding chute and made for low-altitude, high-velocity flying. It’s pretty outrageous. Pilot Alexandre Mulle recently posted this video to his YouTube page as he navigated the famous “Crack” line in Switzerland, most often flown by pilots in wingsuits. Not this time.
