Or, once the defect grew to sufficient size, it might drop straight down like this tower of wooden blocks:
This, despite being incompressible elements compared to the impulse the mass elements can exert on each other in a gravity-driven collapse. Contact points with adhesive which fails under bending and torsion would mimic welds and fasteners snapping.
When there are compressible elements (deformable steel lattice with an interior volume of mostly air), there would be an even greater propensity to drop downward since there is a crush path available, whereas incompressible elements are just that.
