"Six hundred feet above a waterfront airstrip, Jeff Boerboon is a blur in a cherry red biplane. The noise of his propeller engine drowns out the cheers of the crowd below, who have spent a beautiful summer afternoon watching him perform a set of aerial acrobatics \u2014 flips, turns, and nausea-inducing spins. But Boerboon has a surprise in store for them. From his seat in the open-air cockpit, he flips a switch and turns on a jet engine, sending his plane rocketing into the sky and leaving behind a thick trail of smoke. For a moment, it looks as though Boerboon and his plane, the Screamin\u2019 Sasquatch, may just keep going into outer space.\n\u201CLook at that!\u201D he exclaims, back on solid ground, pointing to the CJ610 turbojet engine affixed the bottom of the plane. \u201CIt\u2019s one of a kind!\u201D\nSEE ALSO: The Undercover Agents You Didn't Even Know Were on Your Flight\nBuilt from a 1929 Waco biplane, the Sasquatch's additional jet engine boasts twice the thrust of its propellor counterpart, raising the plane\u2019s top speed from 110 to 250 miles per hour.\n\u201CSeeing that biplane with a jet noise, it doesn\u2019t compute,\u201D Boerboon says, smiling as he imagines the crowd\u2019s reactions, \u201CIt takes a minute.\u201D\nBoerboon, who was the 2010 U.S. Unlimited Aerobatics champion, flies with John Klatt Airshows, a traveling circus of planes and pilots currently making the rounds across the U.S. He started stunt flying more than 20 years ago while studying aviation at the University of North Dakota. His excitement for flying \u2014 and particularly for flying the Screamin\u2019 Sasquatch \u2014 is obvious from the moment you meet him.\n\u201CIt\u2019s nothing but a thing,\u201D says Boerboon, in a Southern accent that makes him sound even more cavalier. \u201CA lot of people think you must be crazy, but I\u2019m the luckiest guy here.\u201D\n\nSubscribe to our YouTube channel for new videos every week."^^<http://www.w3.org/2001/XMLSchema#string>
