Really? Like, I guess there's not too much pressure pushing the gas out in this kind of balloon, but gas is still light and doesn't need much of a push.

    But it's a huge balloon, and it will take a long time for the gas to leak out. The balloon will sag, and drop steadily, but it will still take an extended period of time to actually reach Earth, where the payload may still be dangerous.
