Why? The atmosphere would leak in slower, since there's pressure inside.

It's not like it's a submarine, nor yet like a space station.
And if anything, there's a mild excess of pressure inside, which
would seem to make it less likely for something to leak in.

True. But then, a really major hull breach in a space station wouldn't
be all *that* much happier a circumstance. And a big wobbly baloon in
a blanket of atmosphere seems less likely to encouter fast-moving objects
nasty enough to *cause* a major hull breach.

Not that you'd get me up in one of them things.
