Thermobaric explosions have ultra low freq. sound-prints. An immense belly feeling impression, ears are not really picking it up from 4 blocks away. At the periphery lines set around WTC 7 by FBI, NYPD and other agencies.
At about the 0:59 mark, a high-pressure explosion occurs in one of the Twin Towers, just below the impact zone, while the building is still standing.
In the Final report on the collapse of the Twin Towers issued by NIST, it appears to attempt an explanation for this explosion by suggesting it is a smoke puff resulting from a pressure pulse inside the building, perhaps from a collapsing wall or ceiling, or sudden opening of a door. (See NCSTAR1-5A, p. 52) However, as can be seen from the screen captures in the video above, it isn't merely smoke and dust being ejected. There appears to be a massive object being ejected along with the explosion.

We're not talking about the average Joe on the street reporting this. We're talking about the BBC reporters. It's the obligation of news organizations to double check the facts BEFORE THEY REPORT IT. Which they claim they did.
Off topic and irrelevant. I am not a reporter on a live TV broadcast.

Bye man.
A petty that you can't bring any solid argument to my floor, while you act as if you possess some scientific background. For such a person it should be an interesting challenge to confront me with good argumentation.
Nevertheless, good riddance.

No external force in a gravitational collapse? Hmm, from the top of my head, I can think of one. Can you?
For our purposes, we will simply say that external forces include the applied force, normal force, tension force, friction force, and air resistance force. And for our purposes, the internal forces include the gravity forces, magnetic force, electrical force, and spring force. While this is a simplistic approach, it is an approach that will serve us well in our introduction to physics...
Internal forces
Internal forces are forces that can act on an object without physically
touching the object. Examples of internal forces include:
the force of gravity
electrical forces
magnetic forces
spring forces

Try the latest secret part of the DuPont Handbook of Explosives. I doubt you have access rights to it.

Gravity is not an external force. Didn't they teach you that in electrical engineering school?

Internal vs. External Forces
And from another source, just so you're clear on this...

You can thank me for the physics lesson later.
It's right there on page 637!
Barometric explosions, like all explosions, save those developed by the silent explosive, Hush-a-Boom, are very loud 100% of the time and can be heard at least 5 blocks away at sea level on a clear day.
DrEugene, try Russian websites (fill in their search engines "Chechnya"), and use Babelfish to try to find the term in Cyrillic for Thermobaric bomb. And Chechnya.... Flattening of their capital by the Russians, after their terrorists murdered all those schoolchildren just over the Chechnyan border in Russia was done with their TB's. Or try Indian ones and use Hindi to English. Or Iranian ones and try Farsi to English. Or go to your local University its Chemistry Department Library and ask assistance in your quest for knowledge, they will help you if asked politely, and after you explained to them, the Why. I doubt you will find more than I told you already, but, who knows, ain't it so? It's still a very top secret subject, but leaks get out, god knows you'll get lucky and find a true patriot somewhere on the way in.
I have no death wish, but let me tell you one thing, in the not so near future you will remember this thread.
