actually, now that you mention it, the sideways "puffs" seem more
consistent with a layer collapse and air being expelled by collapse
compression than by numerous discrete dynamite explosions.
and my memory tells me i actually saw a simulation that properly account
for the sideways "puffs"

my first thought when watching the collapse live on TV was "pancake
instability". lots of fellow physicists had simular thoughts. many of us
were wondering what the mystery was all about.

check out the american society for civil engineers site, i recall they
had a fairly extensive list of pointers to simulations, many of which i
looked through a year ago.
