They're now saying the boy was hiding in a box up in his attic. Okay!! Let's get CPS involved! This was nothing more than a Leave It To Beaver moment. I think it'll come out the dad was building this as some kind of weather balloon experiment (he is a storm chaser), and he just got his kid's involved in the process. He blew this thing up to test it for leaks and see how it would look while it was fully inflated. His only mistake was to go inside and leave two curious little boys alone with what they saw as a very cool and giant toy balloon. So of course one or both of them started messing with the tether cables, and this thing took off. What would your normal response be if you had just let daddy's VERY expensive balloon loose? RUN AND HIDE!! They probably didn't even realize what was going on the entire time this event was unfolding. When he heard his parents screaming for him, he probably thought it was because he was in trouble for letting the balloon fly off. The kid is six. Unfortunately, this will probably be a very expensive lesson for Dad. I'm sure the authorties will find a way to bill him for all their search and rescue efforts.
