I have been thinking over what was going on in Nashville since yesterday morning. The first thought that crossed my mind was minimal damage. One video with dashcam footage showed a good fireball with a little black smoke. I am not a demolitions guy, but after the silos in Beirut exploded, I noted the red/orange cloud indicative of NOx emissions. That signaled to me that there was probably ammonium nitrate involved. I don't know what a balanced ANFO reaction looks like, but my guess is that you are always going to get a red cloud of toxic bleach-like gas. This is the same stuff that turns the sky red in polluted cities. From the videos which I have seen, there hasn't been any of that (correct me if I'm wrong), and the block wasn't leveled. If you're going to set off a car bomb to do damage, you're probably going to pick ANFO or some high explosive like dynamite or TNT. The result is going to be half of the building being blown apart like the Murrah Building in OKC. The other thing is that this bombing happened in a city in between two rows of relatively high buildings. That confines the blast and should do a lot more damage because the expanding gases don't have a lot of places to go. Here, we see no crater and just some broken glass and charred grounds. AFAIK, no one was harmed.

It just occurred to me that there was an unexplained propane truck explosion just a few days ago in New York. MSM link. If the Nashville explosion was indeed propane, was this a test run to see how much was needed or how big of a primary explosion was needed to do just enough damage? Think the difference between the Doom map Barrels o' Fun and someone dropping MOAB. If the gas burns slowly, you end up with a bonfire. If everything goes up at once, you end up with more property and people hurt.

Some things that I have considered:

• This "took out" an AT&T building, and crews are trying to restore power to the building. These buildings were built to handle X psi of pressure for a nuclear blast and remain operational. I haven't done any research on this particular building, but it looks like one built in the '60s. It's all brick and concrete. There isn't much combustible in there. Diesel is VERY hard to ignite.
• Since there was no crater, and there was footage from across the street and down the street, how was there enough damage to destroy the buried power infrastructure?
• If, say, 5% of the comms on Christmas Day were taken out, it should get the attention of a lot of people.
• If you have ever been through the Chesapeake Bay tunnel, there is a big red sign that says no propane.
• This gives BBQ agencies an excuse to ban RVs going into DC and possibly subject them to illegal searches. Yes, illegal searches, but they have pulled out all the stops.
• Once you have started searching a ton of vehicles, if nothing else, you have created massive traffic jams.
• Is this a test for a partial communications blackout?

Just a few thoughts. Feel free to shoot down any of these theories or add your own.
