23. The WTC was a sealed building - all the windows were closed

if the air cannot escape all at once it will be compressed. At the WTC4 million cubic feet of air went somewhere in a matter of seconds. It over pressurized the building below the collapse front and blew out a handful of windows.

NIST explains them as pressurized puffs of air gyroscope Jan 2012 #3
so you can tell from that picture that the puff is "exiting out of a single window"? zappaman Jan 2012 #4
Since they are actually explosives gyroscope Jan 2012 #5
how and when exactly sabbat hunter Mar 2012 #60
"they would be blowing out of ALL the windows of the floor" - No. Bolo Boffin Jan 2012 #6
So this 'jetting material' just happens to resemble gyroscope Jan 2012 #7
As I explained, they do NOT resemble precisely timed explosions Bolo Boffin Jan 2012 #8
Do you require glasses? gyroscope Jan 2012 #11
Please stop the sarcasm. Bolo Boffin Jan 2012 #12
Why would they need to cut the outer walls? hack89 Jan 2012 #17
there were in fact a lot of renovations going on in the towers NoMoreWarNow Apr 2012 #68
Feel free to back this up with some evidence. nt hack89 Apr 2012 #69

There are reports of the air blowing down much further than that during the collapse. Bolo Boffin Jan 2012 #10
Something else they can't to explain gyroscope Jan 2012 #14

So these 'puffs of air' as you call them gyroscope Jan 2012 #18
Do you understand compression? hack89 Jan 2012 #19
Compression requires an airtight seal. gyroscope Jan 2012 #20
No, it doesn't. AZCat Jan 2012 #21
"the installation of the charges took place at night and/or on the weekends when people weren't work zappaman Jan 2012 #22

The WTC was a sealed building - all the windows were closed hack89 Jan 2012 #23
No. jesters Jan 2012 #24
Because of where the elevator and HVAC shafts terminated? hack89 Jan 2012 #28
maybe you and gyroscope can settle this and then get back to the rest of us OnTheOtherHand Jan 2012 #29
the 'puffs' come out of the windows in regular demolitions - see Rosa Luxemburg Mar 2012 #56
But the venting in the WTC buildings don't "puff," they jet Bolo Boffin Mar 2012 #62
Why weren't the plotters smart enough to put the cutter chargers hack89 Jan 2012 #13
There would have been some destructive devices along the core. Obviously. jesters Jan 2012 #25
more importantly zappaman Jan 2012 #26
Why would they need them on the exterior walls? hack89 Jan 2012 #27
Simple. gyroscope Jan 2012 #30
So a table can stand with only two legs on one side? hack89 Jan 2012 #31
Don't you forget what you said gyroscope Jan 2012 #32
So if you "need all four 'legs' to hold the table up" hack89 Jan 2012 #33
But it wont come straight down gyroscope Jan 2012 #34
If the core of the tower collapses straight down while the perimeter remains stationary hack89 Jan 2012 #35
So you agree that the core sank first. jesters Jan 2012 #36
Too many damaged columns further weakened by fire hack89 Jan 2012 #37
Lol. jesters Jan 2012 #38
The professional building community has been discussing these issues for some time. AZCat Jan 2012 #39
You do understand why highrises have fireproofing and sprinkler systems? hack89 Jan 2012 #40
Lol. jesters Jan 2012 #41
Only one needed to sag. hack89 Jan 2012 #42
Hack says that "Buildings are not designed with vertical static loads in mind." jesters Jan 2012 #43
Levitation? gyroscope Jan 2012 #46
Sorry - meant vertical dynamic loads. Now answer my question. nt hack89 Jan 2012 #49

You cut out a big chunk of the core hack89 Jan 2012 #48
