I have to agree with the Aussies here. They are over-rating the blast by a bit. I guess I still have a few questions like...
1) Why was that AN just left there for SIX YEARS?! Didn't the Lebanese have some fields that could have used that AN to increase crop yields?
2) Why are they storing explosives in such close proximity to people's residences? Why were there no real precautions taken at the AN warehouse?
3) Why in the H**L did they put explosives next to a stack of giant Grain Elevators? Anyone who knows anything about Grain Elevators, or Corn Silos or Coal Towers knows those things don't need ANY HELP EXPLODING. Even ordinary FLOUR is explosive under the right circumstances. I'm just shocked the Grain Elevators didn't blow as well. That would have generated a nuclear-style blast.
The Halifax and Texas City blasts were similar in scale and would have done about the same damage had they happened at Beirut. Here's a video of a 2K bomb being used on Taliban Insurgents for comparison.
