not sure if they are illegal.
my wifey and i sent one off for her dog that we had to put down, she wrote little notes on the balloon and put some ashes in it, was a nice way to send him off.
they go pretty high on a calm night and are supposed to be safe, cause they only land/crash when the fuel is empty.
on a windy day they wont work, the fuel isnt strong enough to withstand high winds without being blown out.
