Real-life UP Story - Boy floats away in helium balloon (thedenverchannel.com)

Looks like it might have a sad ending -- the boy might have fallen out while the balloon was adrift.

For reference, the balloon has landed, but with neither the basket, nor the boy. Searchers are looking, including the possibility that he was never in the basket.

However, this is not HN - flagged.

The boy has been found in his attic at home, alive.
