The is a simple illustration of why the collapse times can be used to pry open peoples minds to the absurdity that is the OCT:

Quarter mile = 1320 feet

WTC1 = 1368 feet        WTC2 = 1362 feet

According to the OCT the top floor of each tower fell THROUGH hundreds of feet of Structural steel and concrete faster than ->

Immediately the muted idling rumble from the V-12 opens up fully and emits a snarl that grows to a higher-pitched thumping note. The prancing horse gulps in as much air as possible and turns all those air molecules into 650 bhp and 485 lb.-ft. of torque. The rear tires spin momentarily, and fight to bite into the asphalt. Easy and smooth on the throttle here because too much wheelspin slows the car down and loses precious time on the clock. Just before the first shift at 44 mph, get to full throttle. In Race Mode, the F1 transmission will swap gears in as little as 150 milliseconds.

Zero to 60 mph: 3.3 seconds.

Quarter-mile run: 11.1 sec. at 133.0 mph.

Unbelievable.

The Enzo has just recorded the best Road & Track acceleration run ever for a road car. Its 0-60-mph run equals the fastest time logged just a month ago by the all-American Saleen S7. And its quarter-mile time and speed pulverize the mighty McLaren F1's numbers of 11.6 sec. traveling at a mere 125 mph past the quarter-mile mark. Wow!
