Here, I did your work for you:
"Authorities began to fear the worst after reports surfaced that a box possibly carrying Falcon may have fallen off the balloon.
A Weld County Sheriff's deputy had said he saw an object fall off the balloon somewhere over Platteville, Colorado, which is in the search area. There was no box attached when the balloon landed at 1:35 p.m"

As for them slashing at it to deflate it - try again. It was already on the ground and wasn't going anywhere. It was a wild attack trying to find the kid INSIDE the baloon.
I watched the whole thing almost from the beginning and the report of the kid perhaps being in a 'box' was already discounted long before the thing landed.
The baloon was constructed to resemble a flying saucer and was a pretty good immitation of one in an early Sci Fi film.
