Everyone [or most everyone] was kept back 600 feet, that's two blocks.
Most everyone had buildings between them and WTC 7.
Few, including Daryl and Craig, heard the explosions.
There is no set sequence of demolition size or timing.
Every CD is tailored to the task at hand.
Oh, come on C7. I could hear a shotgun easily at 600 feet.
The sequence of any supposed CD of WTC 7 would include (if the hypothesis of those who subscribe to a CD collapse is the case) those that blow columns 79, and/or 80, and/or 81 and/or the transfer trusses and perhaps followed by those that blow the interior columns not only at the lower floors but at intervals all the way to the top and then there are the ones that produced the 'squibs' which go off after the north wall has started to drop.
How many would that be then Chris 7?
Was there only ONE? The 'thunderclap' was the only one heard? Just ONE?
In the much bigger buildings , WTC 1 & 2 we are told that the boom,boom,boom was evidence of demiolitions but there is no boom,boom,boom at WTC 7. So, only ONE boom?
However, the sound, at least that one sound, could be an explosion. It is by no means a given though since it could also be a steel member giving up and snapping. We also have no way of knowing the timing of this sound do we? Did it occur before the east penthouse started to sink or after it had already began to plunge? Since we do not know then it could also be the equipment in the east penthouse breaking free and impacting the 47th floor. It also appears that the falling of the east penthouse initiated the separation of the east and west portions of the building( there is a natural shear plane there. taking out a few columns would increase the likihood of such a separation along that plane since it would be weaker than any other plane) and the 'thunderclap' could then also be the east section separating from the west.

a demolition involves dozens - even hundreds - of charges going off in rapid sequence. A "clap of thunder" won't cut it
In the video Chris 7 supplies above the narrator says "hundreds". Chris 7 might not agree.
The narrator also states tha the building fell in 6 seconds which is a blatant lie. That completely ignores the interior failures that are part and parcel of the collapse. Something happened well before the east penthouse starts to sink inward. The time it took to collapse MUST start at the time this initial failure occured. The 6 seconds is just the time it took for the north facade to fall, some to the south and some to the north.
As for the manner of collapse it does fall almost within its own footprint. Significant damage is done to 30 West Broadway and other debris does impact the buildings to the east and west and WTC 6 to the south. This is a fairly compact area but is it direct evidence of a CD?
No, it isn't. The building's initial failure occured in the interior of the building and progressed through the core. This would cause the building to fall inward on itself. But the south wall was already damaged and thus weakened and that would cause that section (the western section) to preferentially also fall southward. I am not sure why the east section went north east.
So we have two bits of circumstantial evidence of CD. The loud bang and the manner of collapse.
These two bits of circumstantial evidence do have other explanations as well though and are therefore not conclusive.
Chris 7 however also states that in regard to the other hypothesis, DD/F, that there is no direct, empirical evidence of DD/F to the area of the initial failure and this is the case for the CD hypothesis as well. There is no direct, empirical evidence of explosives being placed or going off in WTC 7 let alone them being placed or going off in the area of the initial failure.
