Circumstances:
The approach to Pellston-Emmet County was initiated in limited visibility due to clouds. On final, the crew failed to realize his altitude was too low when the airplane struck trees and crashed in flames few miles short of runway threshold. The aircraft was destroyed and all six occupants were killed, among them Walter Reuther, President of the American Union of Workers in the Automotive Industry.
Probable cause:
Illusions produced by the lack of visual cues during a circling approach over unlighted terrain at night to a runway not equipped with approach lights or other visual approach aids . These illusions, which made the pilot think that he was higher than his true position, were made more acceptable to him because of a strong possibility of an erroneously high indication on his altimeter.

Circumstances:
On a night cargo flight from Detroit to Chicago, the crew encountered technical problems with the left engine that failed. The crew feathered its propeller and was cleared to divert to Kalamazoo Airport for an emergency landing. On final approach, the crew was unable to lower the gear so the captain decided to make a go-around and increased full power on the right engine when the airplane lost height and crashed in Portage, about 2,5 miles southwest of the airport. The aircraft was destroyed and both crew members were killed.
Probable cause:
Failure of the left engine in flight for undetermined reason. Loss of control during a go-around manoeuvre after the crew failed to obtain flying speed as the flaps were fully deployed. The following findings were reported:
- Powerplant failure for undetermined reason,
- The pilot-in-command failed to obtain/maintain flying speed,
- The pilot-in-command misused or failed to use flaps,
- Improper emergency procedures,
- Suspected mechanical discrepancy,

- Improperly loaded aircraft-weight and/or CofG,
