You're skipping a link in the chain. What we are seeing there isn't propane tanks, it's explosives. The damage was done when that blast damaged cooking equipment and starting fires. The fires were fuel (whether it was propane or not I do not know), the boom was not.I thought it was determined that the secondary explosions came from tanks of propane being used for heating and cooking.Could be the bomb struck in one corner of the building destroying that section of the building and the energy from the explosion forced its way down corridor(s) of the remainder of the building and possibly through closed doors and out some window(s) milliseconds later. Couldn't it? Concrete walls and wooden doors might make this scenario possible.A gif in the wiki article about the strike in question (that he posted, mind you) clearly shows a secondary explosion.I'm not finding what I was after so I'll go from memory on it. They dropped a bomb on a commander and it detonated a bunch of explosives on the ground.
I guess we all see what we want to see.
What report are you referring to? What honest report could even exist? Hamas isn't going to be honest and nobody else has access to do it. What we do have:Who did the investigation, and where is their report?
1) The video that has already been linked. Perfectly ordinary case of a secondary from hitting explosives. Since the era of televised war we have seen a lot of such footage.
2) Israel has said the warehouse went up with a considerably larger bang than what they dropped.
3) The reporting from on scene says the deaths were due to fire from damaged cooking equipment spilling fuel.
I see no reason to get fancy here, we have an event that's happened many times before. It's just this time it caused a fire.
