35,000 feet, with the lethal force coming from the difference between the cabin pressure and the atmosphere. Those forces are not present even at the top of skyscrapers as tall as the twin towers, limiting the destructive energy of a conventional bomb to its size.
By the time Reiss had run up one flight on the escalator, he guessed that a truck bomb must have blown up somewhere around the trade center.
Reiss no longer worked in the basement, as he had in 1993, and he wondered, fleetingly, who in his old department had arrived for work on the 88th floor of the north tower. Up there, no one had illusions about a truck bomb. The moment arrived as a powerful fist rocking the building. As soon as Gerry Gaeta, a member of the team that oversaw construction projects at the trade center, could find his words, he hollered, “It’s a bomb, let’s get out of here.” And he was sure he knew how it had gotten up there. Moments earlier, a messenger had arrived with a trolley of documents for Jim Connors in the real estate department. Surely that was how the bomb had been wheeled in, Gaeta thought; the boxes of “documents” had been a Trojan horse.
Down the hall, Nicole De Martini had just drawn the last sip of her coffee and had risen to leave her husband’s office to go to hers, in the south tower, when she and Frank heard a boom from overhead and felt the building lurch. Nicole watched a river of fire spill past the window in Frank’s office. It was a bomb, they both thought.Or maybe the machine room had exploded, burning diesel fuel. Nothing else could explain the force they felt, one that seemed directly above them.
The elevators had rocked, swinging like pendulums. Pasquale Buzzelli, a Port Authority engineer going to his office on 64, felt the car right itself, then slowly descend to the 44th floor, where he had started from. Smoke began to pump through the shaft. No one seemed to understand what was happening, so he got back on the elevator, which now was working just fine, and rode up to the 64th floor. There he met his boss, Patrick Hoey, the engineer in charge of the Port Authority’s bridges and tunnels, who was just as puzzled.
“What happened, Pat?” Buzzelli asked.
“I don’t know, but it near knocked me out of my chair,” Hoey replied.
The tower had miles of elevator shafts. In one that served the middle of the building, six men were in a car bound for the upper floors. They felt the jolt, then a swoop. A window washer named Jan Demczur punched the emergency stop button. In a moment, fingers of smoke crept into the car, rising past the cuffs of the men in the car, pushing down from the roof. They rang the intercom. No one answered. On board another elevator, which had just left the north tower lobby, was Judith Martin, the secretary who had lingered outside for a cigarette. She and six other people were now stuck, pressing the alarm and calling for help.
In the Marriott Hotel, tucked between the two towers, the Rev. Paul Engel, naked except for a cross dangling on a chain around his neck, had just gone to the lockers after working out when he heard an impossibly loud screech of metal on metal, like the squeal of train brakes. A Catholic priest, Engel went every morning to the health club atop the hotel. Normally, he finished his exercise with some laps in the pool, but had skipped that part of his routine today. Now he quickly pulled on the nearest garment, his swimming trunks, and peeked at the pool. It was on fire.
From a window on the 61st floor in the north tower, Ezra Aviles had seen everything. He knew it was no bomb. His window faced north, and he saw the plane tearing through the skies, headingstraight for the tower. It had crashed into the building over his head—how far, he was not sure. In fact, its lower wing cut the ceiling of the 93rd floor, and its right wing had ripped across the 98th floor, at the very moment that Patricia Massari was speaking to her husband about her home pregnancy
