Skip to comments.Balloon at center of Falcon Heene drama not your average hot air balloon

The homemade balloon contraption that soared through the air in eastern Colorado for several hours is vastly different from the giant hot air balloons that are seen at festivals and that are used for recreational purposes, experts say.
Nearly all the giant balloons that drift and bob through the air are hot air balloons that are filled with air and fueled by propane, explains Howard Freeman, executive producer of the Quick Chek New jersey Festival of Ballooning in Reddington, New Jersey. As the air inside the balloon heats up to a temperature higher than the outside air, the balloon rises, he explains. Helium balloons rise because helium is lighter than air, he explains. The contraption, owned by Richard and Mayumi Heene, may have risen even higher than it would have otherwise since the heat would have caused the helium to expand further, Freeman explains.
Both hot air and helium balloons typically are piloted by a pilot with a license, he says.
"A skilled pilot licensed by the Federal Aviation Authority can go to different altitudes and although he can't steer a hot air balloon, a pilot can get it going in the general direction that he wants," Freeman explains.
Hot air balloons generally have 70,000 cubic feet of volume, are seven stories high, and can carry 760 to 800 pounds, or about four adults, Freeman explains.
The flying saucer-shaped silver balloon owned by the Heenes looked to be carrying about 1,500 cubic feet of helium, Freeman estimates. "Some experts are saying that it could not have carried anyone over 70 pounds," he says. "You figure that it takes about 1,000 cubic feet of helium to give you 40 pounds of lift."

Is this an individualized Congressional balloon (self powered by hot air)?
In retrospect I am happy the ‘rescuers’ slashed the balloon.
I think they knew they’d been had, before the landing.
has that reporter never heard of a helium balloon??
There was no way that ballon could hold 1,500 cubic feet of helium.
400 - 500 cubic feet max. 500 would be 5 x 10 x 10 (if it were a box)
Assuming 500 cubit feet then max lift is 30 pounds. Knock off about 8 pounds for the weight of the aircraft and you could lift about 22 additional pounds on a good day. The kid looks 60 pounds to me.
LOL! Apparently not. We are also regaled with the stunning revelation that hot-air balloons are filled with air that has been heated. Who knew?
That is quite the investigative journalism
no, I must correct you, that is a Hot Air Baffoon
Splash and dash!
That is a poor explanation.
From the dolt-scribe's POV, better than we serfs deserve. LOL!!
I am just not sure what this story had to do with hot air baloons. Nothing as far as I can tell. I guess this article was for the idiots who voted for Obama.
4/3 X pi X radius cubed.
I was having a hard time estimating the size of the balloon but guessed it was about 16 feet across. If you plug in the numbers you come up with 6400 cubic feet, but that is for a spherical balloon not a disk shaped one. One cubic foot of helium can lift 28.2 grams so if you divide the total grams lifted by 448 grams that equals the pounds lifted. A 16 foot diameter balloon could lift about 145 pounds. Since this balloon is flattened disk shaped it looks like its maybe 1/3 the volume of a spherical one, then it could lift 45 pounds. The kid and the balloon would have to weigh less than this. Can't wait to see this on Myth Busters.
Maybe, but I'm inclined to believe you're just being cheritable.
zerO's voters could neither read or comprehend print, never-mind the spoken word. LOL
Yep. The article wasn’t dumbed down enough for them.
"It is ba-llooon!"
Did you know that you can make hot air by heating air that is at room temperature? true story.
