Cory Lidle's plane crashed in New York because the pilot misjudged a narrow U-turn before veering into a Manhattan high-rise, federal investigators said Tuesday. In presenting their findings, National Transportation Safety Board investigators said they still don't know whether Lidle or his flight instructor was piloting the plane at the time of the Oct. 11, 2006, crash. Investigator Lorenda Ward told board members that the turn above the East River could have been made safely if the plane had begun the turn further east or banked harder in the turn. "With the proper planning, judgment and airmanship the 180-degree turn was possible," Ward said. The pilot sought to correct the turn but instead lost altitude as the plane headed into Manhattan, she said. "The increase in bank angle was too late," Ward said.
