I didn't see the first missile strike on the base of the left hand side of the frame. I did see a near vertical strike directly from the top for the second explosion, this was Definitely a projectile of some sort, you can step through the frames and see it coming from above and right down through, curiously, it may have been some kind of bomb, there was no propulsion trail; kinda reminded me of the Hand of God, kinetic weapon because on sectional density and the fact that a detonation occurred at the bottom of the building instead of starting at first impact. The third missile detonated at the base of the right side of the building, couldn't see the trajectory, but you could definitely hear it coming.
