It’s clearly something thrown up at a high velocity during the first milliseconds of the blast, followed by the smoke of the explosion.

Did not look outbound to me. For it to be outbound and the building is 15 stories high that outbound object has to be some 3 hundred feet in the air.

At this point I would say that object was most likely inbound and is the source of the explosion that follows. I would not rule out a meteor strike but there is definitely something weird going on with this.
