Since my post last night, it appears that the authorities have determined that it was all a hoax. Once the balloon landed and they were able to examine it up close, based on the materials of which it was constructed, experts determined that it was impossible for the balloon to have carried Falcon aloft.
Why did the parents concoct this farce? The local sheriff surmises that it was "a publicity stunt done with the hopes of marketing themselves or better marketing themselves for a reality television show at some point in the future." People really are crazy.
