A news helicopter from Philadelphia crashed in Wharton State Forest in New Jersey, killing the pilot and photographer onboard.

The cause of the crash is being investigated by the Federal Aviation Administration (FAA) and the National Transportation Safety Board.

The helicopter had completed an assignment on the Jersey Shore and was returning to Philadelphia when the crash occurred.

The pilot and photographer were experienced individuals with a long history with the news station.

The helicopter was leased from US Helicopter and was being used for news coverage by 6ABC.

The crash site is difficult to access due to heavy foliage and its remote location, delaying the investigation until morning.

The final report on the cause of the crash may take a year or more to be released.
