How could there have been explosions in the lobby at the "exact moment" of impact, when cascading jet fuel or magical fire balls require a certain amount of time to travel down 800 feet? The two events you describe could only occur simultaneously if the explosions at the alleged point of impact on the 79th floor and the explosions in the lobby were two separate events.
Thedman, I don't deny that kerosene can be explosive, but to the extent seen on so many different lower floors? Not a chance.

The energy density of Jet A is approximately 43 MJ / kg (remember that number for later). The typical yardstick, TNT, is a mere 4.2 MJ / kg, ten times less. Exotic, impractical, high-powered explosives such as octanitrocubane only get up to about 7.5 to 8 MJ / kg, still a factor of five below Jet A. It really doesn't matter what explosive compound you fantasize about, they just aren't going to give you more energy than the jet fuel, unless you propose a fantastic amount of it. I can only assume you don't know much about explosives.

24,000 pounds of fuel is the estimate that NIST gave for the amount of fuel running into the lower structure. NIST estimated that there were 66,100 pounds of fuel in AA11 and 62,000 pounds in UA175 at impact (NCSTAR1-2B, pg. 171). Of those totals, NIST estimated that 20% was consumed in the initial fireballs, 40% was distributed on the impact floors, and 40% drained or flowed into the lower structure (NCSTAR1-5F pg. 56).
For an elevator’s cables to be cut and result in dropping the car to the bottom of the shaft, the cables would need to have been in the aircraft impact debris path, floors 93 through 98 in WTC 1 or floors 78 through 83 in WTC 2. Inspection of the elevator riser diagram and architectural floor plans for WTC 1 shows that the following elevators met these criteria: cars 81 through 86 ( Bank B ) and 87 through 92 (Bank C), local cars in Zone III; car 50, the freight elevator, and car 6, the Zone III shuttle. …Cars 6 and 50 could have fallen all the way to the pit in the sub-basement level, and car 50 in WTC 1 was reported to have done so.(NIST NCSTAR1-7, p.160 - PDF)
Two of the interviewee's associates were injured by flying concrete block on the B2 and/or B4 levels when the 50 Car elevator crashed to the bottom of WTC 1. (NIST NCSTAR1-8, p.80 - PDF)
Elevators 6A and 7A were out of service for modernization. (NIST NCSTAR 1-8, p.43)
[The Griffiths] were both operating elevators in the north tower on Sept. 11. Arturo was running 50A, the big freight car going from the six-level basement to the 108th floor. When American Airlines Flight 11 struck at 8:46 a.m., Arturo and a co-worker were heading from the second-level basement to the 49th floor.
Like his wife, who had just closed the doors on a passenger elevator leaving the 78th floor, Arturo heard a sudden whistling sound and the impact. Cables were severed and Arturo's car plunged into free fall.
"The only thing I remember saying was 'Oh, God, Oh, God, I'm going to die,' " he says, recalling how he tried to protect his head as the car plummeted.
The emergency brakes caught after 15 or 16 floors. The imploding elevator door crushed Arturo's right knee and broke the tibia below it. His passenger escaped injury. (USA Today)
ARTURO GRIFFITH, WTC SURVIVOR: I was running 58 cars -- the elevators that going to 86 to 108th floor.
KING: Where were you when it happened?
A. GRIFFITH: Well, I was on my way from B-2 to 49th floor. And as I took off, it was amount it was a matter of seconds -- five, six, seven seconds, I don't know. And there was a loud explosion and the elevator dropped. And when the elevator dropped there was a lot of debris and cables falling on top of the elevator. And I just -- I just put my hand over my head and I said, oh God I'm going to die. But I didn't know what was happening.
When the elevator finally stopped, they had an explosion that bring the doors inside the elevator, and I think I'm sure that that was what broke my leg. And then they had another explosion and the panel that threw me, you know, against the wall, and I guess I was unconscious for a couple of minutes because somebody else was in the elevator with me, and they say that they was trying to get my attention and they didn't get no response from me.

Arturo Griffith was in a freight elevator when the building was attacked. The elevator dropped to B1 (the basement level), fell below the landing. He was trapped in the elevator beneath debris and unconscious. He remembers seeing a beam of light. He called out. The smoke was so thick; Arturo could not see his own hand. So his rescuers had to follow his voice to find him.
'I don't know who saved me. It was so black and smoky. I couldn't see nothing',' Arturo said. 'When they got me out, I told them there was someone else down there, a woman. They went back to get her. Seconds after they pulled her out, a ball of fire came down the shaft. They almost got killed.' (Source link)

Ginny Carr WTC2 Impact Audio Recording - The Doppler Shift Problem
Ginny Carr was at a business meeting in One Liberty Plaza on the Morning of September 11th 2001. The proceedings were recorded with her voice dictation machine and she accidentally recorded the WTC2 impact sound.
The engine noise recorded is not reminiscent of the roaring sound that should have been produced by the 2 bypass engines used on a Boeing 767-200 and reveals no noticeable Doppler shift.
But the drop in pitch of the engine noise should have been even more pronounced than it was in the Ginny Carr WTC1 Impact Audio Recording due to the relatively higher airspeed of the UA175 aircraft and its closer proximity to One Liberty Plaza. This can only imply that the sound source was either stationary, traveling very slow or was approaching One Liberty Plaza from the west of the World Trade Center complex.
If you listen closely to the recording you will notice that the engine noise continues after the impact sound and fades away gently. This effect could have been caused by acoustic reflections off the high rise buildings in Lower Manhattan.

"...Yasana Mutuanot...was in the lobby of Tower One when she heard the first explosion. Thinking it was a bomb like the terrorist attack in 1993, she turned to run, looking over her shoulder as flames leaped from a freight elevator shaft cooking her back and legs and right cheek.
""It was a fireball with sand and heat, like a hurricane of fire," she said.
"The lobby windows shattered as she stumbled out of the building and fell. She could not regain her footing. Her husband, who had not yet entered the building, arrived at her side.
""I kept asking my husband, `Did I lose my foot? Did I lose my foot?' " she said.
"The foot was still attached, but the Achilles' tendon had been severed by debris. She hobbled away with her husband and eventually found an ambulance...."
NEW YORK - While the city continued the grisly process of identifying the dead Monday, burn patients in a New York hospital recalled fireballs bursting from elevator shafts at the World Trade Center, setting human torches.
"I saw a lot of people with fire on their back and in their hair," said Yasana Mutuanot from her bed in the burn ward at New York Weill Cornell Medical Center, where she is being treated for burns over half of her body. "It was like a movie of Vietnam, like napalm or something. . . . There was a man who lost his shirt and pants. The skin on his face was all bubbled and on his body, too. You could see the skin peeling off."
Mutuanot was among 25 burn patients at the hospital, probably about half of the severe cases from the disaster and a quarter of the total cases scattered among city hospitals, Weill Cornell Medical College Dean Dr. Antonio M. Gotto estimated. Hospitals had been prepared for a huge influx of patients that never came.
Except for the burn patients and a few trauma cases, such as a woman on a sidewalk struck by one of the plane's landing gear, people either walked away largely unscathed or were incinerated by the exploding jet fuel or crushed to death in the rubble.
Mayor Rudolph Giuliani raised the number of missing to 5,422 and said 211 others were confirmed dead. Of those, 135 had been identified. Thirty-four of those were New York firefighters, one was a New Jersey firefighter, two were emergency medical technicians and two were Port Authority police officers.
Giuliani urged families of the missing to take DNA samples in any form they could find - toothbrushes, hair, unlaundered underwear.
But the mayor also asked families to begin considering the possibility that many of the missing may never be found.
"The simple reality is we're not going to be able to recover significant numbers of people," he said. Dr. Roger Yurt, head of Weill Cornell's burn unit, said three patients had died since the disaster. One, he said, died of shock early on. Two more died of lung damage from smoke inhalation. The rest have burns over 50 to 90 percent of their bodies, and are extremely susceptible to infection.
"Every one of these patients still has a long way to go," Yurt said. "They won't be considered out of the woods until their wounds are healed and that will be three months down the line. . . . It's a lifelong thing. They'll always have scars."
Yurt said those within 10 floors of the jets' impact were probably incinerated. The burn victims were either at the margins of the exploding jet fuel or hit by the blast of flame that careened down elevator shafts. Yurt recalled one man's story of being trapped in an elevator as flames swept in, burning half his body before he escaped to walk down 70 floors.

The foot was still attached, but the Achilles' tendon had been severed by debris. She hobbled away with her husband and eventually found an ambulance.
Mutuanot and the man from the elevator were the only patients in the burn unit who were well enough to tell their stories, Yurt said. Most of the others had tubes between their vocal cords and were hooked to ventilators.
Ronnie Clifford and Jennianne Maffeo
At around 8.45am, Ronnie walked into the lobby of the Marriott, which was connected to the lobby of the north tower by a revolving door. As he was checking his yellow tie in a mirror, he felt a massive explosion, followed several seconds later by a reverberation, a warping effect that he describes as the "harmonic tolerance of a building that's shaking like a tuning fork". He peered through the revolving door into the lobby of the north tower. It was filling with haze. People were scurrying to escape what had become a "hurricane of flying debris".
(MISSING)
Then the revolving door turned with a suctioning sound followed by a hot burst of wind, and in came a mannequin of the future. A woman, naked, dazed, her arms outstretched. She was so badly burned that Ronnie had no idea what race she was or how old she might be. She clawed the air with fingernails turned porcelain-white. The zipper of what had once been a sweater had melted into her chest, as if it were the zipper to her own body. Her hair had been singed to a crisp steel wool. With her, in the gust of the door, came a pungent odour, the smell of kerosene or paraffin, Ronnie thought. (more)

Ronnie Clifford was still whispering the Lord's Prayer in Jennieann Maffeo's ear when the second plane hit. The whole edifice rumbled and groaned and swayed, then the floor beneath him buckled hideously and seemed to raise him off his feet. Pieces of the building began falling around him. Ronnie knew then that they absolutely must get out.
Among the ticketed passengers on American Airlines flight 11, the first plane, the one that hit the north tower, had been Paige Farley-Hackel, his sister Ruth's best friend and a close friend of his.
A little later in the afternoon he was able to verify an even more devastating fact: Ruth and her four-year-old daughter, Juliana, had been on the second plane, the United Airlines flight from Boston.
Finally, maybe the most important account regarding the lobby is this:
Ronnie Clifford and Jennianne Maffeo

As he was checking his yellow tie in a mirror, he felt a massive explosion, followed several seconds later by a reverberation, a warping effect that he describes as the "harmonic tolerance of a building that's shaking like a tuning fork". He peered through the revolving door into the lobby of the north tower. It was filling with haze. People were scurrying to escape what had become a "hurricane of flying debris".
(LT: this bolded part is now MISSING!)
Yet Ronnie remained untouched. It was as though the revolving door were a glass portal to another realm, a world of chaos and soot just inches away. The Marriott lobby was calm, the marble surfaces polished and antiseptic. For a few seconds, the two adjacent worlds did not meet.
Then the revolving door turned with a suctioning sound followed by a hot burst of wind, and in came a mannequin of the future. A woman, naked, dazed, her arms outstretched. She was so badly burned that Ronnie had no idea what race she was or how old she might be. She clawed the air with fingernails turned porcelain-white. The zipper of what had once been a sweater had melted into her chest, as if it were the zipper to her own body. Her hair had been singed to a crisp steel wool. With her, in the gust of the door, came a pungent odor, the smell of kerosene or paraffin, Ronnie thought. (Source)
The revolving door is just across the south side of elevators 6 and 7. If they were the origin of the blast, then why didn't he see a fireball emerging from there, then why is the glass still intact? But the glass on the west front is broken. And the marble panels on the west-wall of the core removed.
This proves that the shafts of 6 and 7 weren't the origin of the damage in the lobby. We have already ruled out elevator 50 for the basement damage. So what's left? A good question. Another good question: Why did Mark Roberts, who published a paper in an attempt to debunk skeptics of the official version, cut out the bolded part of the statement? Of all lobby-accounts the most incriminating part for the official version.
What is he hiding from us? And why is he hiding from us? And why has never footage been released showing the south side of the lobby, which certainly exists, or should we believe that despite all the footage of the lobby, nobody made even one picture of the zone, which according to the official version, should have been the most damaged one?
"On Sept. 11, falling debris knocked out the 22nd-floor security center's equipment just after the plane hit, says Mr. Reiss, who is still with the Port Authority and was helping with the transition to new management that took over the complex in July. The guards, who had to be rescued themselves, couldn't have buzzed anyone through to the roof. Even after the building's electricity was cut off, internal batteries in the electromagnetic locks would have kept the doors closed for several hours, Mr. Reiss says. (Source)
This command center controlled the Closed Circuit TV (CCTV) of the WTC complex, the HVAC (Heating, Ventilation and Air Conditioning)system and the access to the roof and the Mechanical Equipment Rooms (MER). Simultaneously with the basement explosions the SCC was disabled due to an explosion, causing more stress and handicaps to the emergency efforts.
Firefighter Michael Yarembinsky:
When we got to 22, we heard there was a Port Authority command post on 22. So we were stopped there. My officer wanted to find out some information, my officer Lieutenant Andy Desperito. He went over to the command post. We noticed in the hallway that the elevator shaft had been blown out. There was nothing there, no doors, no framing, nothing. When you looked down, all you saw was the cables for the elevator and the brick work that was surrounding.
Q. Was it burning?
A. No burning, no smoke coming out of it. (Source - PDF)
And from William Rodriguez we know, that the OCC wasn't even manned when he was there, before the second plane hit:
QUOTE
I find water all over, run straight to the south tower where they have the OCC (operation control center) that was created after 1993. They spent $155 million to retrofit the building, and to supposedly straighten it out after the 1993 bombing, and to set up a whole security system, the control center. When I got there and started hitting the window there was nobody there. There was nobody there—the control center, where they have all the cameras, and the recordings. (Source)

I repeat, when she started to run, after the first explosion she heard and felt, she was not hit by a JET 5 fuel-air fireball, but by something else, likely the terrible effect of thermobaric explosions.
Third.- Do we know for certain that none of the elevators fell down completely without the emergency braking??
Cause we are talking many elevators here. So maybe one or two did fall down to basement levels or the lobby crashing down there. (And causing what some people have confused with explosions.)
