Minnesota

The crew was engaged in a routine cold war training mission out from Loring AFB, Maine. While cruising by night at an altitude of 36,400 feet over Minnesota State, the tail broke off and the airplane went into a dive. In 108 seconds, the heavy bomber descended at high speed to the altitude of 8,000 feet before crashing in a huge explosion in Inver Grove Heights, about 7,5 miles south of Saint Paul. The aircraft was totally destroyed but one crew member survived while seven others were killed.

At approximately 0329LT, the airplane crashed on takeoff from Wold-Chamberlain Field, Minneapolis, Minnesota. A number of the 62 persons (including 2 infants) aboard suffered serious injuries but there were no fatalities. Fire, which broke out a short time after all occupants were evacuated, consumed the aircraft. The aircraft took off normally and climbed to a height of about 100 feet. It then gradually nosed over and entered a descent which continued until it struck the ground. Sky conditions were clear; however, the prevailing visibility was about three miles in fog, and in localized areas around the airport it was reduced to lens than a mile by patches of denser fog. Takeoff was made on runway 22 and the climbout was a from a lighted, built-up section toward an open, unlighted area. The Board believes that the pilot while trying to remain contact in reduced visibility allowed the nose of the aircraft to drop when flaps were retracted because of inattention to flight instruments. The darkness and reduced visibility during climbout contributed to a sensory illusion which completely obscured the fact of descent from the pilot.

Northwest Airlines' NC93037 departed from the Minneapolis- St Paul International Airport at 0946LT on a local flight. The purpose of the flight was a six-month instrument competency check of Captain John R. Galt under the supervision of Captain Ray Render, a company cheek pilot. Also on board and listed as official observers were William H Solomon, CAA air carrier agent, who was sitting on the jump seat between and immediately behind the pilots' seats, and CAA personnel from the Minneapolis Control Tower, E. Bergstrom, R. Olsen and B. Erickson, who were sitting in the main cabin. At the time of takeoff there were 800 gallons of fuel on board which resulted in a total aircraft weight of 32,943 pounds. This weight was within the allowable limit of 38,000 pounds and the aircraft was properly loaded. The weather was clear and visibility was unlimited. Following takeoff, two simulated US (Instrument landing system) approaches were made to the airport and at 1025LT the crew radioed the control tower that this phase of the check flight was completed. This was the last known contact with the flight. After departing the Minneapolis area, the aircraft was first seen near Center City, Minnesota, 43 miles northwest of Minneapolis. At this time it was making a steep left turn at an altitude estimated to he between 4,000 and 5,000 feet, and landing gear was down. At the completion of this turn a shallow climb was started. Throughout these maneuvers the engines sounded as if they were operating in a normal manner. The attention of the ground witness was then diverted for a few moments, and when he again saw the aircraft it was in a partially inverted position and starting a steep dive. After losing approximately 2,500 feet in the dive, an apparently normal recovery was made to a level flight attitude and the aircraft proceeded in a northeasterly direction. Shortly thereafter it was seen to make two or three pitching oscillations about its lateral axis. These maneuvers may he described as a series of steps made by the aircraft as it was being lowered abruptly, followed by a recovery to level flight. During each oscillation approximately 400 feet in altitude was lost and a noise was heard such as is usually associated with a surge of engine power. The aircraft continued on a northeast heading. Two miles south of Almelund, Minnesota, which is 14 miles northeast of Center City, the aircraft was seen to make a shallow right turn of approximately 270 degrees and once more to return to a level attitude heading in a northwesterly direction. Throughout the above-mentioned maneuvers, the aircraft was gradually losing altitude, and the right propeller was observed to be turning slowly during the latter part of the flight. Nearing Almelund and at an altitude of approximately 500 or 600 feet above the ground, a steep right turn was begun. Altitude was lost rapidly and after turning approximately 90 degrees, the aircraft's right wing struck the ground. All but one of the six occupants were killed at impact, the injured person died several days later without regaining consciousness. The aircraft was demolished.

Shortly after takeoff from Minneapolis-St Paul-Wold-Chamberlain Field Airport, while climbing in poor weather conditions, the captain decided to attempt an emergency landing for unknown reason. The aircraft crash landed in a field and came to rest with the left engine on fire. All 31 occupants were able to vacate the cabin and there were no injuries. The aircraft christened 'The Haylift Express' was damaged beyond repair. All passengers were members of the Reserve Officers Training Corps (ROTC) of the University of Minnesota.

The aircraft departed Washington DC at 1230LT destined for Winnipeg, Manitoba, Canada, with intermediate stops in Detroit, Rochester, Madison and Minneapolis. With the exception of an hour and 23 minute delay at Detroit, required for the replacement of a ring seal in the hydraulic system, the flight proceeded in air routine manner to Madison, Wisconsin After arrival at Madison the aircraft was serviced with 1,010 gallons of fuel and 38 gallons of oil. Also on board were 10 passengers and 1,799 pounds of cargo which resulted in an aircraft weight of 36,842 pounds. This weight was well within the allowable limit of 39,100 pounds, and so far as is known, the aircraft was properly loaded. Weather information available to the flight prior to its departure from Madison showed that Rochester, 75 miles south southeast of Minneapolis, was reporting a ceiling of 700 feet with visibility of five miles, and that Minneapolis was reporting a ceiling of 900 feet with visibility of 1/2 mile 3. In addition, there was fog and blowing snow at these stations. Turbulence was expected in the clouds, and icing above the freezing level of 8,000 feet. The trip was planned to Minneapolis at an altitude of 4 000 feet, the schedule stop at Rochester being made contingent upon weather conditions at the time of the flight’s arrival. Madison, Wis., and Jamestown, N. Dak where weather conditions were well above landing minimums, were designated as alternate airports. Flight 307 arrived over Rochester at 2023, and because there was light freezing rain, did not land. Twelve minutes later the flight made a routine report to company radio that it was over Stanton which is a radio beacon 30 miles south of the Twin Cities Airport at Minneapolis, and at 2041 contacted Minneapolis Approach Control for landing clearance. The tower advised Flight 307 of existing, weather conditions. There was a precipitation ceiling of 900 feet, visibility was variable 1/2 to 3/4 of a mile, and the wind was from the north 27 miles per hour with gusts up to 40 miles per hour. The tower informed the flight that there had been two electric power failures at the field, and that if no further communication were received from the tower, it would be in all probability the result of another power failure The flight was also told that the ILS was serviceable, but that it had not been flight checked. As Flight 307 approached, another NWA flight, a Boeing 377, was standing at the approach end of the instrument runway, Runway 35, checking engines prior to flight Takeoff clearance was given to the Boeing 377. When it had proceeded half-way down the runway, Flight 307 reported that it was over the outer marker, which was 4.7 miles south of the approach end of the runway. The high intensity runway lights were increased in intensity, their coning device was set to 1/2 mile, the prevailing visibility at the time, and Flight 307 was cleared to land. Flight 307 was not seen from the tower during its approach, but it was heard to pass overhead at which time the controllers received the call, “I have got to get in Clearance was again given to land, following which the flight advised that it would climb to 2,400 feet on the northwest course of the Minneapolis radio range. After a pause, the flight transmitted. “We are going in-we are going in.” After the aircraft had flown over the field, it was observed flying straight and level 3.8 miles northwest of the airport. A wing was seen to fall. Then, the aircraft was observed to dive almost vertically from an altitude of about 300 feet, and crash into a residence in the city of Minneapolis Fire which started immediately after the crash consumed the house and much of the aircraft wreckage. All of the 13 occupants of the aircraft and two of the occupants of the house were killed.

During a training flight, an engine failed. The captain was unable to maintain a safe altitude and ordered all crew tom bail out. Out of control, the aircraft dove into the ground and crashed in a field. All ten crew members were unhurt while the aircraft was destroyed.

The airplane departed Minneapolis-Wold Chamberlain on a flight to Seattle with several intermediate stops. Approaching Fargo-Hector Field at night, the crew encountered icing conditions. The airplane became unstable and pitched up and down. The captain increased engine power when the airplane stalled and crashed in a prairie located in Moorhead, bursting into flames. The airplane was destroyed by a post crash fire. A pilot survived while 14 other occupants were killed.

The single engine airplane departed Fargo-Hector Field on a weather mission over Minnesota. While cruising at night at an altitude of 15,000 feet, the airplane entered an uncontrolled descent and crashed in an open field located some 5 km north of Moorhead. The aircraft was destroyed and both occupants were killed.

The single engine airplane crashed in a field in Saint Paul shortly after takeoff from Minneapolis-World-Chamberlain Field. There were no casualties.

Shortly after takeoff from Minneapolis-Saint Paul Airport, while climbing, the airplane suffered an multiple engine failure. It stalled and crashed in a garden located in Mounds View Boulevard, bursting into flames. A passenger was killed while all other occupants were injured. The aircraft was destroyed.
