A Child Floating Away in a Balloon?

The balloon reported to be floating across Colorado with a 6 year old child trapped in it has finally landed:

The bizarre scene played out live on television and prompted fears that the mushroom-shaped balloon would crash. The balloon rotated slowly in the wind, tipping precariously at times.

The boy's family had been building an experimental aircraft that had a large helium balloon attached to it at their home, KUSA-TV reported. The aircraft, which resembled a flying saucer, was approximately 20 feet by 5 feet and had a foil top.

The balloon is down now and they are saying there was no kid in in it when it landed.

Remind never to build a big balloon like that in my backyard. I hope the kid never actually got on the balloon.
