> Bleed holes, Captain Joe explains, “allow for pressure equalization between the space between the panes of the window and the cabin interior. Without these holes, the pressure difference between the cabin and the space between the panes would lead to stress on the window.”
Doesn't this just put the stress on the other pane of the window? I don't see how it helps.
EDIT: Oh. It helps because otherwise the bit between the panes would be at a different pressure to both the interior and exterior of the plane. It would work just as well if the bleed hole were on the outside, as long as both panes are equally strong.
so if I block it with my finger from takeoff to cruise I can create a little explosion? Or is the issue the repeated cycles of pressure weakening the material over time?
The article claims it helps stop condensation, but I have several memories of little ice crystals and/or condensation that originate right at the little hole…

I'll definitely be on the lookout next time I fly though but yeah. Maybe its not every window?
