This. Is. Incredible! Alexander Polli continues to advance the field of human flight with the first-ever successful wingsuit target strike. Yes, you read that correctly. A fixed target strike… in a wingsuit. At speeds of 155 MPH (250 km/h), Polli explodes through precisely placed foam slalom gates as he flies his wingsuit down the steep Swiss slopes. Forget about “grinding the crack,” he shreds it!
