Yes, I know it was obscured by the smoke, and the billowing of the dust from the collapse. BUT, most of the South Tower is also blocked from view by WTC 7. Still, there are no "flashes", nor any sort of "explosions", just the deep sort of rumbling sounds one would expect in the collapse sequence.
As to the "CD' comment....Um, from your OP:
You can clearly hear the explosion and see a flash just before the tower
starts to fall.
Pardon me for thinking that, in that sentence, you implied a "CD". Did you or did you not imply such?
"Drip, drip, drip..." That sorta cemented the idea and intent of your posting, no?
"There's the third"
"The thrid plane hit it"
"I thought I saw stuff projecting out the right"

It does "change the thread"....because, an example of the deep sound (or even as commented by others, "several"...but not the typical rapid-succession heard in known CD events) that YOU call an "explosion" is nothing more than an indication of internal structural collapse, and the sounds that accompany those events.
Watch, and listen, carefully. This was a tragic (because three people were killed) accident involving a crane that suffered a structural failure. Apparently, it was loaded BEYOND its bearing capacity, and failed globally. (OR, it was designed improperly, and loaded to "designed" tolerances...but, nevertheless, it failed spectacularly).
Pay attention that, despite the "sounds" of "explosions", there WERE NONE!!! Just, the SOUNDS of stuff breaking, and "sounding like" an "explosion"....
This is clear, as an example. Because it isn't covered up with the dust that is inherent in a huge office buildings' collapse, what with all the other furnishings and drywall and all that other stuff that's part of such buildings. This, a bare and nude crane, made out of STEEL, that broke and the SOUND of the breaking made NOISES thta resembled "explosions".
Which is EXACTLY what happened to the Twin Towers that fatfeul morning.

How can you honestly say that when so much of the building is obscured by smoke? Isn't it a bit speculative to say which happened first?
Look at 1:42 of the video....
What your hearing there is the cables snapping , the king pin failing then the crane collapse and the cameras mic is right up close.
Referring back to the video in your OP....ummmmm....the sounds of the helicopter, in the opening seconds OF THAT VIDEO, indicate a certain "directionality" of the mic associated with the video. Does it not??? However, given that the chopper is in a relative position to the camera (and thus, the recording apparatus...the "mic") compared to the South Tower, and their relative distance FROM the recording device (this case, the camera/mic combination)....do you not yet comprehend how it is important, and also, somewhat deceptive??? I am not sure I have the proper terminology to explain what, to me, is plainly obvious....from life experience.
Really, from my life experience i thought that the closer you were to a noise the louder you heard it.
And a really loud noise can be heard further away.
Oh and by the way the camera was pulling out not zooming in...

Makes my point even better.
The entirety of the soundtrack, as the camera zoomed IN, back out....you CANNOT judge the actual soundsof the event, based on the evidence form ONE camera/video soundtrack example.
JUST AS I mentioned, with Hollywood!! I do wish you'd pay attention, and realize that those mentions are not meant to distract, but to provide examples to compare to.......edit on 10 October 2010 by weedwhacker because: spell

I don't know why the NIST wanted this video since I don't see anything truly significant. The flash could have been from any number of things. I'm not familiar with the John Grosse incident so I'd prefer not to speculate much on it although it does seem odd. The only clear portion of the video is the beginning with the helicopter and close up of WTC 1. I'm also somewhat curious about the audio in the video as the acoustics change like a cut although the video doesn't. It appears to be shot as a hand held video as opposed to using a tripod so I wouldn't expect the narration to change unless the video matched to some degree.

How can you even tell exactly where the collapse began to compare it with sound? We're not talking about seconds here but presumably milliseconds. A millisecond or few for sound, another couple for the collapsing debris to break through the smoke and whatever other variables are present and I just can't say or see anything concrete regarding this from the video. I tried to find the flash, frame by frame, and see how it related to the noise but my capturing program seems to miss the frame with the flash. It's doubtful that we're going to see eye to eye on this one.
