The comments on the story are great. Appears if people applied somephysics to the problem they would have figured out the boy probably wasnot in there to begin with (source Bret Hodgson):
The diameter of the balloon : 15ft
the height of the balloon: 6ft
volume of a cylinder : 7.5 * 7.5 * PI = 1059.75 cu. ft ... Read More
account for saucer shape : ~ 70% of cylinder volume = 741.825 cu. ft
weight 1 sq ft of helium can lift: 28 grams
total lifting power of the baloon at 741.825 cu. ft. = 20,771 grams
convert grams to pounds: 45 lb and 12.67 oz
average weight of a 5 year old boy (taken from
http://babybag.com/page-height.html): 44.5lbs
Given the above, it looks technically possible for a balloon of thissize to lift said child. However, I believe this to be very unlikely.
