1 MT = 1,000Kg = 2204.62 pounds.
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.

I’ve witnessed 15000 pound BLU-82’s dropped, B52 bombing, conventional ALCM, thousands of pounds of comp b, C4, TNT and dynamite blow and I do not ever recall seeing a shock wave move that fast.

The quote I read was 2750 TONS. 2.75 Kilotons.
Over 6 million pounds of Ammonium Nitrate. >400 of those BLU-82's going off all at once.

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.
