225 that NIST interviewed. NO utility shafts directly connected the strike zone with this level. That shaft contained Car 50, and Car 50 held two occupants that survived and did not describe a destructive fireball after the plane impact. I have found NO explanation in any part of the NCSTAR 1 report -- diagrammatic, computer simulated, schematic -- that hypothesizes how this could have happened. The occupants of Car 50 were injured after the car fell several floors, were rescued, and lay in the vicinity of that shaft for up to 40 minutes before being evacuated. Neither they, nor their rescuers reported a destructive fireball. With the car stuck in the shaft around subbasement level 2 or 3, a fireball descending the shaft could not have reached sublevels 4, 5, or 6 where extensive damage has been reported by several eyewitnesses. Something else took place which NIST left completely unexplained. Deaths and injuries appeared in front of the elevator banks that ran to the thirtieth floors in the West Street lobby, with the doors blown off and the shafts exposed. The express elevators in the lobby to the fortieth floors, on the south side of the lobby, and those to the 78th floor, on the north side of the lobby were reported by Lt. William Walsh as undamaged. Elevators further into the building to the twentieth floors were still operative. None of this is explained with a plausible route jet fuel fireballs may have taken through shafts for elevators or
