Six-Year-Old Boy Thought Trapped in Balloon Now Missing

After initial reports that Falcon Heene was trapped inside a homemade aircraft flying near Fort Collins, Colorado, the six-year-old is now missing.

The Heene family — which appeared in the 100th episode of ABC's Wife Swap — was constructing an experimental 20-foot helium balloon attached to their home earlier today, and it was initially believed that young Falcon boarded the "flying saucer," which is capable of ascending to about 10,000 feet.

After accidentally taking off, the aircraft landed about 40 miles from where it took off two hours later.

The Heene family — which includes two other young boys — is described on Wife Swap's website as "storm-chasing" and "science-obsessed" and has constructed earlier "experimental aircrafts."

"When the Heene family aren't chasing storms," the site continues, "they devote their time to scientific experiments that include looking for extraterrestrials and building a research-gathering flying saucer to send into the eye of the storm."

A rep for ABC tells, "We are not issuing a statement, but we can confirm that the boy believed to be involved in the flight is Falcon and the family did appear on Wife Swap."

Late this afternoon, police were conducting a ground search for Falcon.
