FORT COLLINS, Colo. (AP) - Rescuers chased a homemade balloon aircraft Thursday afternoon in Colorado, under the belief a 6-year-old boy was inside.
Rescue crews surrounded the balloon that landed in a field after two hours in the air. According to a sheriff's official, the boy climbed into box attached to balloon, but basket nor the boy were found at crash.
Authorities feverishly searched for any sign of the child, including in the neighborhood where he lives.
Cathy Davis of the Larimer County Sheriff's Department told reporters the balloon was owned by the boy's parents and tethered behind the family's home.
She said two sons were playing outside when the older boy saw the younger one go into a compartment at the bottom of the balloon and fly away.
Live footage from a local TV helicopter showed the balloon gliding quickly through the air and prompted fears about the fate of a young boy.
Larimer County sheriff's spokeswoman Eloise Campanella says the device, which is shaped like a flying saucer, has the potential to rise to 10,000 feet.
FAA spokesman Mike Fergus says the agency has been notified and it was unclear whether traffic controllers had picked it up on radar.
