Mike Pecoraro... The 36 year-old father of two stopped and bought breakfast on the way into One World Trade Center and changed into his work clothes.
Deep below the tower,Mike Pecoraro was suddenly interrupted...
His co-worker made the call and reported back to Mike that he was told that the Assistant Chief did not know what happened but that the whole building seemed to shake and there was a loud explosion... By this time, however, the room they were working in began to fill with a white smoke.
The two decided to ascend the stairs to the C level, to a small machine shop where Vito Deleo and David Williams were supposed to be working. When the two arrived at the C level, they found the machine shop gone.
"There was nothing there but rubble, "Mike said. "We're talking about a 50 ton hydraulic press ? gone!"
The two made their way to the parking garage, but found that it, too, was gone. "There were no walls, there was rubble on the floor, and you can't see anything" he said.
They decided to ascend two more levels to the building's lobby. As they ascended to the B Level, one floor above, they were astonished to see a steel and concrete fire door that weighed about 300 pounds, wrinkled up "like a piece of aluminum foil" and lying on the floor. "They got us again," Mike told his co-worker, referring to the terrorist attack at the center in 1993... He was convinced a bomb had gone off in the building... Mike ascended to the Lobby Level where he met Arti DelBianco, a member of his work crew.
He walked out into the main lobby of the building, seeing it for the first time.
"When I walked out into the lobby, it was incredible," he recalled. "The whole lobby was soot and black, elevator doors were missing. The marble was missing off some of the walls. 20-foot section of marble, 20 by 10 foot sections of marble, gone from the walls". The west windows were all gone. They were missing. These are tremendous windows. They were just gone. Broken glass everywhere, the revolving doors were all broken and their glass was gone. Every sprinkler head was going off. I am thinking to myself, how are these sprinkler heads going off? It takes a lot of heat to set off a sprinkler head. It never dawned on me that there was a giant fireball that came through the air of the lobby.

The jet fuel actually came down the elevator shaft, blew off all the (elevator) doors and flames rolled through the lobby. That explained all the burnt people and why everything was sooted in the lobby.
Snip~
From the Chief Engineer magazine and reports of eyewitness account of the moments after the first plane crash describing evidence of large explosions in the lobby, parking garage and subbasement levels of WTC-1 at the time of the crash.
The two decided to ascend the stairs to the C level, to a small machine shop where Vito Deleo and David Williams were supposed to be working. When the two arrived at the C level, they found the machine shop gone.

NO WAY that burning jet fuel falling could do all that. However, BOMBS COULD!

The only realistic and feasible explanation for free fall at the WTC in existence.

The reason the basement explosives were detonated on plane impact (vibration sensors) was to divide the seismic spike between 2 events.

Why do you think that was so? in anticipation for 9/11, or in case of a disaster like a hurricane?

Agreed. btw, if that is your website, you might want to make your fonts smaller. it's kind of hard to read and quickly glance through.

You must be on a PC. You would be the first to mention that. The font size is basically set for the default browser settings ( I thought). Is your browser set large?
Deep below the tower, Mike Pecoraro was suddenly interrupted in his grinding task by a shake on his shoulder from his co-worker. "Did you see that?" he was asked. Mike told him that he had seen nothing. "You didn't see the lights flicker?", his co-worker asked again. "No," Mike responded, but he knew immediately that if the lights had flickered, it could spell trouble.

If there were explosives in the basement, how come he didn't notice when they went off?
All of the damage described is consistent with a fuel air explosion in the freight elevator shaft.

I bet you think that the 50-ton hydraulic press weighs 50 tons.

You left out his part of the story

Since when do fuel-air explosions destroy any presses, wrinkle up 300-pound steel and concrete doors as if they were aluminum, and knock out reinforced concrete basement walls, all hundreds upon hundreds of feet from the ignition?
Fuel-Air Explosives [FAE] disperse an aerosol cloud of fuel which is ignited by an embedded detonator to produce an explosion. The rapidly expanding wave front due to overpressure flattens all objects within close proximity of the epicenter of the aerosol fuel cloud, and produces debilitating damage well beyond the flattened area. The main destructive force of FAE is high overpressure, useful against soft targets such as minefields, armored vehicles, aircraft parked in the open, and bunkers.
Fuel/air explosive represent the military application of the vapor cloud explosions and dust explosions accidents that have long bedeviled a variety of industries.
Accidental vapor cloud explosion hazards are of great concern to the refining and chemical processing industry, and a number of catastrophic explosion accidents have had significant consequences in terms of injury, property damage, business interruption, loss of goodwill, and environmental impact.
There are dramatic differences between explosions involving vapor clouds and high explosives at close distances. For the same amount of energy, the high explosive blast overpressure is much higher and the blast impulse is much lower than that from a vapor cloud explosion. The shock wave from a TNT explosion is of relatively short duration, while the blast wave produced by an explosion of hydrocarbon material displays a relatively long duration. The duration of the positive phase of a shock wave is an important parameter in the response of structures to a blast.
Although the detonation combustion mode produces the most severe damage, fast deflagrations of the cloud can result from flame acceleration under confined and congested conditions. Flame propagation speed has a significant influence on the blast parameters both inside and outside the source volume.
The blast effects from vapor cloud explosions are determined not only by the amount of fuel, but more importantly by the combustion mode of the cloud. Significant overpressures can be generated by both detonations and deflagrations. Most vapor cloud explosions are deflagrations, not detonations. Flame speed of a deflagration is subsonic, with flame speed increasing in restricted areas and decreasing in open areas. Significantly, a detonation is supersonic, and will proceed through almost all of the available flammable vapor at the detonation reaction rate. This creates far more severe peak over-pressures and much higher amounts of blast energy. The speed of the flame front movement is directly proportional to the amount of blast over-pressure. A wide spectrum of flame speeds may result from flame acceleration under various conditions. High flame front speeds and resulting high blast over pressures are seen in accidental vapor cloud explosions where there is a significant amount of confinement and congestion that limits flame front expansion and increases flame turbulence.

So, if you read it, how come you don't understand it?
The descriptions of the fires and flames in the elevator shafts, the damage to the doors and equipment at the bottom of the shaft are all consistent with the description of the blast effects of a FAE.
