More juicy stuff. Seems like the pilot tried to cover it up:

"The controller handling the flight turned his attention to other
traffic. When he checked again on Flight 1883, Halleran said, he saw
the jet rolling slowly on Taxiway Zulu, just north of Runway 29. That
was a little unusual - if the plane were headed to the terminals, it
would likely have used a taxiway to the south, Halleran explained. So
the controller radioed the pilot to ask what happened. According to
Halleran, the pilot answered: 'I just cleared the runway. Now I'm
taxiing west on Zulu.'"

"'The controller didn't think much of it at that point,' Halleran said.
But then, the tower got a call from a frightened employee at a Port
Authority building next to the taxiway. 'We just had some airplane go
by on Taxiway Zulu real quick,' the caller said. The controller
notified his supervisor. In a radio conversation with the supervisor,
the pilot quickly admitted he'd missed the runway and landed on the
taxiway, Halleran said."

"The cockpit voice recorder would have picked up any talk between the
pilot and co-pilot. But the recorder operates on a half-hour loop, and
the plane was sent on other flights before the voice recording could be
removed, officials said."
