If you think about it, a spacecraft only really needs to handle about 1 atm of pressure, which isn’t much compared to something like a deep sea submersible that needs to handle 100+.

That’s only fifteen PSI.

My tires have forty.

Yeah, they could probably even go a bit lower than sea level pressure.

Though even then, it would still be like everything outside was a giant vacuum cleaner. How thick would a pane of glass on earth need to be if you stuck a massive vacuum cleaner over it that managed a perfect seal around the window so that the window didn't shatter even if you bump it a bit on the other side?

I was going to add that a strong hurricane can result from just a 10% pressure difference, but I realized that it's a bit misleading because while that is accurate for the pressure driving it, the destruction that hurricanes cause from winds is more about the momentum of all that air moving to equalize the pressure, not the acceleration from pressure difference itself. It's probably easier to engineer a bay window for a spaceship than a bay window to watch a (strong) hurricane make landfall through. Other than all the space crap slamming into it, at least.
