@farmerman,
2The ballons bouyancy WAS never an issue becauae several "Expwerts" had done calculations and (one guy even went to the specs of the balloon from its ad in magazines and the internet).
--------------------------------------------------------------------------------------
Experts experts you pick the experts however I will go with the laws of physics.
In any case below is a news story that they had found experts that claim the balloon could indeed not go up with the boy.
As I said who need experts when it is simple physic but what the hell as you seem to worship at the alter of experts here is one for you.

Balloon at center of Falcon Heene drama not your average hot air balloon

Both hot air and helium balloons typically are piloted by a pilot with a license.

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."
===========================================
Helium balloons are flown by licensed pilots and if they are not, they could pose a potential problem to planes and helicopters, says Ken Tadolini, a hot air balloon pilot, FAA certified balloon repairman, and owner of Rocky Mountain Hot Air in Denver. They are used more for long distance, competition purposes, he says.
"This is the first time I have seen anything like this," he said of the Fort Collins contraption. "What is very disturbing is knowing the potential for disaster here. If anyone was in the balloons, they could have hit power lines. It was lucky that it had a really soft landing, nice and easy. Not five minutes later, in that same field right where the balloon landed, there was a dust devil that created a circular moving column of air and would have turned that balloon upside down if it had been landing."
Another potential problem if a balloon goes too high in the air is that its occupants can have difficulty breathing, Freeman explains. He said he believed the Heenes' balloon only ascended to 8,500 feet. "But between 10,000 and 12,500 feet, you can get hypoxia, which is the technical term for a lack of oxygen."
