A small factoid, but interesting to me. What’s a other 281.356 tons, give or take? To put things into perspective, the Oklahoma City bombing used 7000 lbs of explosives....or 35 US tons. Thus, the difference in measurement between metric tons and US tons in Beirut was 8 times larger than then ENTIRE Oklahoma City bomb.

Another way of looking at it: A 2000-lb bunker buster bomb (BLU-109, actually weighing 1,927 lbs) contains 530 lbs of high explosives....or .240404 metric tons of explosive. I'm no kind of explosives expert at all, but if my math is right, then Beirut explosion was roughly the equivalent of 11,439 2000-lb bunker busters going off, minus the shrapnel.

That said, knowing dock workers, and how pitiful OSHA type organizations are here in the States, I doubt it is going to be much more than a sad chain of events that caused this to happen. Some poor schmuck was likely doing work in a bad conditions with little to no formal training and zero safety training. This coupled with what is apparently criminal negligence in storing so many Haz-Mat in the same area which could fuel the triangle for an explosion.

Don’t see a need to chase bogey men down a rabbit hole.

If the ammonium nitrate was on the floor of the warehouse at ground level, why did the explosion create a deep crater? Seems like the force of the blast at ground level would have completely collapsed the adjacent grain elevators.

2750 MT = 6.06 million pounds

I don't believe it is correct to equate atomic bomb yields which are measured in terms of equivalent weights of TNT (Kilotons). This would only be correct if the energy yielded by 1 measure of TNT is equal to the energy released by exploding the same measure of Ammonium Nitrate.

The sound of supersonic plane/missile is can be clearly heart few seconds before the explosion. This is the first attack, resulting in the first small explosion of the ammo depot. There is another video that may show the second attack wave.
Most likely the couple taking video did not make it, but I am not certain.

I didn't hear any aircraft. The video starts with the building already on fire. The fire grows and a smaller explosion happens from inside the building. I heard air drafting, but no aircraft or bomb. But, I could be wrong, of course. Not long after the first explosion, the second bigger explosion. Again, nothing that sounded like an aircraft.

@Beiruty ... Very glad to hear that your family is mostly ok. I was thinking about you most of the day yesterday and was glad to read your posts here. Best wishes to the Lebanese working to recover from this disaster.

This video seems to imply that the explosion was at that "Site 1" by Netanyahu showing a potential target on the "waters edge" and then showing the blast on the waters edge however, I did a quick lookup on a map and the explosion is a bit farther north, up the coast. On the map linked below you can see where the airport is and that little site 1 peninsula and where the blast site is.

Site 1 and all the maps are not where the explosion happened. It is another place, a small marina south of Beirut, near the airport.
