A homemade balloon that was thought to have been carrying a six-year-old Colorado boy thousands of feet in the air above The Rockies has landed — and little Falcon Heene wasn’t inside. The Denver Post is reporting that the boy got into the device at his family’s home in Fort Collins and that it then came loose from its tether.

When authorities approached the landed balloon, it was reportedly found to be empty.

Falcon’s parents, Richard and Naomi Heene, and the rest of family appeared on the 100th episode of the ABC reality show Wife Swap in March 2009. The show site described the Heenes as a “storm-chasing, science-obsessed” family. E!’s Joel McHale later made fun of Richard for blowing up at his “replacement wife” while she nagged him on an episode of The Soup.

Here’s a video of Falcon and his older brothers appearing in a mock music video.
