Hampton Friedman told the station that he saw the woman jump from the moving plane.

"I look over and sunlight and I just see a figure essentially step out of it," he said. "And then I'm like what was that."

Passengers sat on the runway for more than an hour as authorities chased down the fleeing passenger.

The FBI was called to investigate, but turned the case over to Houston police after concluding there was no federal case.
