What happened
While traveling toward Mitchel AFB on Long Island, the flight crew encountered deteriorating weather conditions that necessitated a diversion to LaGuardia Airport. Upon reaching LaGuardia, the crew determined that landing was not possible because of dense fog. Consequently, the decision was made to proceed to Philadelphia-Northeast Airfield.
During the night approach at the secondary destination, the aircraft struck a swampy area approximately one mile before reaching the runway. The impact resulted in three fatalities among the crew members. All three passengers on board were successfully rescued from the wreckage.
