Summary

Description
English: Figure 9–122. Landing gear found at the corner of West and Rector streets

It is believed that a portion of the main landing gear of AA 11 exited WTC 1 at the 94th or 95th floor and landed at the corner of Rector and West Streets. This debris is believed to be a tire, wheel, brake assembly, and hub of a main landing gear, as shown in Figure 9–122. Based on the final position of the landing gear and assuming the landing gear to be a projectile with a horizontal initial velocity, the exit speed of the landing gear from the south wall of WTC 1 can be estimated to be about 105 mph. Note that there is a significant uncertainty in this estimate associated with the exit trajectory, aerodynamic effects, landing position rather than final resting position of debris, etc. Another piece of landing gear debris, shown in Figure 9–123, was found embedded in what is postulated to be the panel containing columns 329, 330, 331, running from the 93rd to the 96th floors. This panel was dislodged from the building and found at Cedar Street near its intersection with West Street. As little other damage had been Global Impact Analyses NIST NCSTAR 1-2B, WTC Investigation 345 documented on the south face of WTC 1, it is postulated that the landing gear debris that landed at the corner of Rector St. and West St. also exited through this panel location.
