I had basically assumed it was over-inflation.<br>What was the balloon actually supposed to be filled to?<br><br>I make it that the balloon diameter at 61k ft is almost exactly 2.5 times the original diameter.<br>(pressure at 61k ft is ~7% of sea level, take inverse of cube root).<br>

In the car on the way back, Mikolaj and I were speculating on what made the balloon burst so much lower than we were hoping. It occurred to me that we could learn a lot from how the balloon burst and what remained intact. Was I right in understanding the retrieval guys brought everything back including the shards of the balloon? Would you be able to bring it on Tuesday so we could have a look at it?<div>
