On Thursday morning, according to the family and officials, the boy got onto the aircraft and detached the rope holding it in place. Sheriff's spokeswoman Eloise Campanella said the boy climbed into the access door and the airborne device took off.
The craft, which is shaped like a flying saucer, has the potential to rise to 10,000 feet, Campanella said. Sheriff's officials last saw the device floating south of Milliken, which is about 40 miles north of Denver.
