FORT COLLINS, Colo. - The 6-year-old boy from Fort Collins, Colorado at the center of the runaway balloon saga got sick twice on national television when he and his father were asked during separate TV interviews what he meant about his comment during an interview on CNN that "we did this for a show."

Larimer County Sheriff Jim Alderman says his investigators believe there was no hoax, but will seek a new interview with the family Friday as a result of the CNN broadcast Thursday to clarify the statement.

During an ABC interview Friday morning, Falcon Heene said, "Mom, I feel like I'm going to vomit." He then left the room with his mother and could be heard gagging.

During a live interview on NBC shown simultaneously on Friday, Falcon threw up into a container when his father was answering the same question.

Falcon vanished around the time that a homemade helium balloon floated away from his home, attracting national and worldwide attention as authorities scoured the plains of northern Colorado for the youngster.

He was found hiding in an attic above the garage five hours after the balloon floated away from the family's backyard in Fort Collins.

The family released video of the balloon as it floated away. You can see the father, Richard Heene, kind of jumping around as the balloon lifts off. He described what happened and where he thought his son might be.

"I was upset that the project was pretty much down the tubes because we had about, I don't know, a couple hundred experiments that we were going to work with," Heene said. "And of course the whole thing was just washed down the tubes."

"Earlier in the day, we had told him (6-year-old Falcon Heene) several times not to play inside it, and finally, I ended up raising my voice telling him not to play in it." Heene went on to say that the little boy seemed to get upset.

Heene said another son, Bradford, told his parents that Falcon was inside the balloon. "So we had no other reason to first not look into it, search the house," he said.

Falcon's mother, Mayumi Heene, said she wasn't sure whether he was in the balloon or not. So, they called police at about 11:00 a.m. Thursday saying their 6-year-old son had floated away in that saucer-shaped, home-built, experimental balloon.

The balloon floated to the ground about 55 miles away in Adams County at 1:40 p.m., and that's when emergency personnel found out the boy was not on board. A little more than two hours later, he was found inside the attic in the house.
