What physical process leads to the buckling effect observed when a booster experiences a gas system failure?

Answer

The thin stainless steel walls lose rigidity under the weight of the vehicle and external atmospheric pressure

When the pressure inside the tank drops or fluctuates unexpectedly due to a gas system failure, the thin stainless steel walls of the booster lose their structural rigidity. These walls are designed to be extremely lightweight, so they rely on proper internal pressurization to remain stable. Once that balance is lost, the metal folds under the sheer weight of the vehicle combined with the force of the external atmospheric pressure.
