@revk@toot.me.uk I would assume any windows designed to contain significant pressure are laminated. It is presumably possible that some layers of the laminated glass are more elastic than others - the

@revk@toot.me.uk also note that in many materials, the yield strength actually increases the more they plastically deform. So imagine a window made out of a material that will behave plastically. At first, the pressure is above the yield strength and it will deform plastically (stretch). This deformation increases the strength and it is now strong enough to withstand the pressure, so it stops stretching. Now bond a weak brittle layer to that - as the window stretches, the weak layer shatters.
