20. (Ref. 1) How much pressure can a spaceship take before it explodes? (A K2S Question)

From The Space Library

The orbiter crew compartment is designed to withstand an interior air pressure of 16 psi. Normally the pressure is maintained at 14.7 psi for the crew to breathe. During ascent the cargo bay is vented to release any trapped air so that pressure is not built up excessively. (Ref. 1)
