Wow! I was laughing my a$$ off till I got to all the pics. That scared the smile right off my face. It hit two couches that could have been full of people. Best display of the need for tether cords I've ever seen.
A guy at work had one take off like that in his buddy's yard a few years ago. Headed straight for his garage, hit the snowpile that had come down off the roof, launched into the air and came down hanging from the skis in the eave trough, and proceeded to rip all the siding off the side of the garage. Funniest story I ever heard....course he embellished the story quite a bit!
