MORRIS TOWNSHIP, N.J. — Investigators for the National Transportation Safety Board say the pilot of a plane that crashed on a New Jersey highway talked with an air traffic controller about icing shortly beforehand.

They say it was only a seven-second call. They are not yet sure if it was to report icing had occurred or to question the location of possible icing conditions.

The plane crashed Tuesday morning on Interstate 287 in northern New Jersey. All five people aboard were killed, but no one on the ground was injured.

Federal investigators say the plane departed Teterboro Airport at 9:50 a.m. and crashed 14 minutes later. It was headed for Georgia was carrying two New York investment bankers and the wife and two children of one of them.
