The crew was engaged in a world tour and the aircraft has been prepared with special equipment. It was able to fly 20 hours without fuel stop. The crew departed Lae in New Guinea bound for Howland Island, in the South Pacific Ocean. The trip was estimated to be 20 hours and it seems that the aircraft crashed into the sea some 30 minutes prior to its arrival at Howland Island. SAR operations never found any trace of the aircraft nor the crew. Both occupants, famous aviation pioneers and aviators, were lost for ever.
Crew:
Amelia Earhart, pilot,
Frederick Noonan, radio navigator.
Probable cause:

Circumstances:
The airplane was completing a night mail flight from Chicago to Seattle with intermediate stops in Minneapolis and Missoula, carrying two pilots and a load of 500 lbs of mail. While overflying west Idaho in poor weather conditions, the twin engine aircraft impacted the slope of a mountain located in the region of Kellogg. The airplane was destroyed by impact forces and both crew members were killed.
Crew:
Joe Livermore, pilot,
Arthur A. Haid, copilot.
Probable cause:
In arriving at a conclusion after an analysis of the evidence, it does not appear that the accident was due to weather, mechanical failure of the aircraft, radio aids or communications, or to any failure of the company to comply with prevailing rules and practices. Full cognizance is taken of the possibility that the magnetic compass may not have been functioning properly during the flight. However, a study of available evidence, this appear improbable. It is the opinion of the Accident Board that the probable cause of this accident was faulty navigation in not following the radio range course upon leaving Missoula and failing to ascent to a safe altitude over the course pursued from Elk River.

The Captain Joseph Sittelle was killed while six other occupants were injured.
Probable cause:
The cause of the crash was attributed to a controlled flight into terrain (CFIT).

Circumstances:
The twin engine airplane departed Saint Louis-Lambert Airport at night and in poor weather conditions. While in initial climb, the crew made a turn to the left at an insufficient altitude, causing the left wing tip to struck the ground. Out of control, the aircraft crashed in an open field located 5 km north of Lambert Airport, bursting into flames. All eight occupants were killed.
Probable cause:
Several theories are suggested as to the cause of this accident. However, there is insufficient evidence to substantiate any of them. It is felt that the airplane was thoroughly controllable and that the turn back in the direction of the airport was a voluntary maneuver. Apparently, the pilot, after lifting the airplane into the air, became concerned either with some unexpected irregularity such as the functioning of some part of the airplane and made a turn toward the airport without realizing his nearness to the ground. However, it is not believed that any condition arose or a severity which would have prevented the pilot from acquiring more altitude before attempting to make a turn. It is the opinion of the Bureau of Air commerce that the probable cause of this accident was making a turn at an extremely low altitude, for reasons unknown, in which the wing of the airplane unintentionally contacted the ground.

Circumstances:
Shortly after liftoff, while climbing to a height of some 20 feet, the left engine failed. The aircraft stalled and impacted the runway surface. Simultaneously, the left engine restarted and the aircraft climbed to a height of 75 feet. At this moment, the right engine failed and the aircraft stalled and crashed past the runway end. Quickly on the scene, rescuers were able to evacuate all eight occupants injured while the aircraft was destroyed. Brand new, it was delivered to Northwest Airlines few weeks ago.
Probable cause:
It is the opinion of the Accident Board that the probable causes of this accident were:
- Failure of the Supervisory Personnel to definitely determine the actual fuel consumption of a new airplane before placing it in scheduled operation,
- Failure of the fuel gauge on the left tank to function accurately,
- Pilot error for failing to attempt to use the right fuel tank after the instrument board warning light had indicated that the task which he was using was about empty. This was his first flight on this type of aircraft as well. At the time of the accident, the crew calculated that the fuel consumption was about 163 liters per hour while the real consumption was about 240 liters per hour.
