You beat me :)
Wasn’t this a Darwin Award entry several years back. The story IIRC was a guy in California tried this and tied a rope to the truck so the lounge chair would only go up 50 or so feet. He had a BB gun and was going to shoot balloons to lower up himself.
Story goes, the rope got loose and the guy floated above LAX.
Great Minds... :)
I wish tapes survived of the airline pilots trying to explain to air traffic control what they just saw.
