I don't get a clear look via my Media Player, but both 'blasts' appear to happen at the exact same time. If one is blowout of another, it would seem there would be a very small dely, but a delay none-the-less. If two bombs the same thing, but your explanation would seem to be right. That would cause a blowout at same time. I'll have to watch.

On the 003 there are 2 or 3 frames on the left explosion before the right.

Then the clear delay is see for a another frame or two.

Not simultaneous, and a DARN GOOD JOB.
