Well, it's hard to say about the cooperation. It's not that
   massive coordination is impossible - I mean, look at your
   average wedding. They actually usually manage to come together
   somehow, although usually involving a cast of characters that
   have lots of practice supporting the neophytes.

   My mother worked in government. The lower levels cooperated.
   Actually, the LOWEST level cooperated. Anything higher than
   lowest level and it was backstabbing, politics, grandstanding,
   far worse than you see in movies describing it.

   Detectives and cops don't get along. Military and criminal
   justice and police don't get along with each other. Different
   jurisdictions fight.

   But let's say there's a single small tactical operation.

   Ok, perhaps a group of 4 or 5 people can cooperate with each
   other well. Maybe even up to 12 people.

   Beyond that, something so precise and coordinated AND invisible?
   I dunno.

   Perhaps if they've had practice blowing up OTHER similar
   buildings in the past - that is, LOTS of practice... I could see
   it coming together perfectly.

   But ok. There's security cameras. Footage. There's stuff from
   other buildings not destroyed. Video tapes. Records. When did
   they practice?

   Who were they?

   They had to stake out the place beforehand.

   Plan their moves.

   Get everything precise.

   I mean, in the movies it's simple. They have cut scenes,
   everything is scripted. There are retakes, do-overs, etc and by
   the time the finished product is edited, everything LOOKS
   coordinated and simple.

   But it's not.

   Maybe... maybe there's a group of people SO IN SYNC with each
   other that they can follow orders precisely... but I find it
   hard to believe.

   Even if everything else lines up logically, the "people
   coordination" aspect isn't something I'd take too "obviously".

   Another example: I worked for Big Pharma for a few years.
   Schering-Plough when it existed. [it's now Merck].

   From the outside, it looks coordinated, organized, stable,
   cooperative.

   Internally? hah. Nothing of the sort.

   You wouldn't know that unless you were on the inside though.
