The main point here is that there is some strange damage here that is consistent with a beam weapon fired from above, but of course these holes do not prove it.
In my view, overall, the beam weapon hypothesis is the best explanation for the accumulated phenomenon associated with the destruction of the twin towers.
Note, the beam weapon was almost certainly not a "laser" but rather a microwave weapon with particular affinity for concrete and steel. The idea is that the beam (or beams) vibrated at the proper frequency to blow apart steel and concrete and turn them into fine dust.
