Capital Airlines Flight 500 originated in Memphis, Tenn., December 12, 1949, and proceeded in a routine manner to Norfolk, Va. No difficulties of any kind were experienced. At Norfolk a new crew consisting of Captain William J. Davis, Copilot Lloyd L. Porter, and Flight Attendant Joseph W. Buell were assigned to the flight for the remainder of the trip to Newport News, Va., and Washington, D. C. Before takeoff from Norfolk, Captain Davis studied all weather data in the Capital Airlines office, and called the company’s dispatcher in Washington who advised him that weather conditions would remain above landing limits until after midnight. Flight 500 took off from Norfolk at 1816; arrived at Newport News, Va., at 1836; and seven minutes later, at 1843, was again in the air en route to Washington by way of Richmond, Va., at a cruising altitude of 4,000 feet. On board were 20 passengers, the crew of three, 792 pounds of cargo and 3,000 pounds of fuel. Total aircraft weight was 25,472 pounds, which was 126 pounds in excess of the certificated aircraft weight. The load was distributed so that the center of gravity of the aircraft was within the certificated limits. The trip continued without incident. It reported over Richmond at 1910, and was then cleared by Air Route Traffic Control to proceed at 8,000 feet to the Clifton Intersection, which is 32 miles southwest of the Washington National Airport. By the time that the flight arrived over Clifton, however, ceiling and visibility at Washington were below landing minimums, so instructions were given to the flight to “hold.” Approximately 410 gallons of fuel remained on board, and weather conditions at the al-ternate airports of Richmond and Norfolk were remaining well above landing minimums. At 2025, a weather observer stationed at the south end of runway 36 at the National Airport reported that the ceiling was 400 feet variable, and that the visibility was 3/4 of a mile. Since landing minimums were now indicated, the control tower cleared one aircraft to land and the Capital flight to descend to 3,500 feet in the holding pattern. The air-craft which had been cleared to land completed its landing at 2033 without incident using the instrument landing system (ILS). At 2033 another runway observation was made, reporting the ceiling to be 400 feet variable, and the visibility 1 1/2 miles restricted by light rain and fog. Immediately following the transmission of this observation, clearance was given to Capital’s Flight 500 to descend to 1,500 feet and to commence its landing approach. Flight 500 acknowledged. Five minutes later, at 2038, the flight reported leaving the outer marker, five miles south of the end of runway 36, at which time it was cleared by the tower to land. From the holding pattern to the outer marker the aircraft was observed in the ground control approach (GCA) radar scopes which are in the Washington National Tower. Nothing unusual was noted. As the flight passed over the outer marker at 1,500 feet, entering its ILS approach, the GCA operator advised that the approach would be monitored. This message, as is customary, was not acknowledged, so it is not known whether either the pilot or the copilot was listening to GCA. In the GCA radar scopes, the flight path and descent at first appeared to be normal. When the aircraft was 4 1/2 miles from its point of landing, it was 200 feet to the right of the intended track, an extended center line of the runway, and the glide was good. When it was three miles from intended point of touchdown, it was 50 feet to the right and the glide was still good. When two miles out, the aircraft was on the center line, and only 25 feet above the glide path. One and one-half miles out, it was on the center line, and on the glide path. Then, the flight began to deviate to the right from the center line. The GCA operator in his monitoring conversation advised the flight that it was drifting sharply to the right, and followed by saying that it had gone 1,500 feet off course. The flight then appeared to turn left, proceeding back to the center line, but when within 1,000 feet of the center line and only 1/2 mile from the end of the runway, it disappeared entirely from the scopes. The aircraft was neither seen nor heard by any of the control tower operators, nor by the weather observer stationed at the end of runway 36. A few minutes after the accident, the runway observer reported the ceiling to be 400 feet variable and visibility to be 3/4 of a mile. There was light rain and fog, and the wind was from the south-southwest at nine miles per hour. The aircraft struck the water, left wing and nose first, in a steep nose down, left turning attitude. Both pilots and four passengers were killed. The aircraft was lost.

The flight departed Burbank, California, at 1420, bound for Oakland and Sacramento, with a crew consisting of James S. Garnett, pilot, Joseph Dillon, copilot and Susan DeVore, stewardess. Takeoff was accomplished from Oakland at 1656 at which time the aircraft carried six passengers, out no cargo. Total aircraft weight was within the certificated limits and the load was properly distributed. The aircraft carried fuel sufficient for a flight of two hours and thirty minutes and the estimated flight time to Sacramento was thirty minutes. Following take off, the flight cruised five miles northwest of the Oakland Airport for seven minutes while waiting for receipt of an instrument flight clearance which provided for a cruising altitude of 4,000 feet to Sacramento. The flight then proceeded on course, and at 1708 reported over the Richmond Radio flange Intersection, 16 miles northwest of Oakland, stating that it would be over the Fairfield Radio flange Station, 41 miles northeast of Richmond, at 1723. Since there was no routine mention of altitude, Air Route Traffic Control immediately requested the information, and the flight replied that at was at 4,000 feet. This was the last communication received from the flight. Approximately one hour after the position report over Richmond, CAA Communications received a report that the flight had crashed six miles east of Vallejo. All occupants were killed and the aircraft was destroyed.

Flight 157 originated at LaGuardia Field, New York, for Mexico City, Mexico, with stops scheduled at Washington, D C., and Dallas, Tex. Departure from LaGuardia was at 2147, November 28 Between LaGuardia and Washington the flight was reported to be uneventful with all of the aircraft's components functioning normally. At Washington, a flight plan was filed with, and approved by, Airway Route Traffic Control It specified Instrument Flight Rules to Dallas, with Wichita Falls, Tex, as the alternate, a cruising altitude of 18,000 feet, and a flight time of 5 hours and 4 minutes The gross height of the aircraft at takeoff was 82,298 pounds, which was 3,577 pounds less than the maximum allowable gross weight of 85,875 pounds, and the disposable load was distributed so that the center of gravity was within prescribed limits. At 0206 the flight requested and received permission to change its flight plan to Visual Flight Rules A posit-,on report was made over Nashville at 16,000 feet at 0254 and a descent was started to 6,000 feet When approaching Nashville, 1 No 1 engine had started backfiring at intervals of about 20 seconds Various corrective measures, including the application of alcohol and carburetor heat, and the richening of fuel mixture, were applied but were not successful and the backfiring continued. The captain and the flight engineer discussed the malfunctioning following which No 1 engine was feathered at a point about 25 miles southwest of Nashville at approximately 0300, however, the feathering was not reported to the company until 0429, where the flight was in the vicinity of Altheimer, Ark, a routine position reporting point about 125 miles beyond Memphis At that time, the crew advised a change of aircraft on arrival at Dallas. When 15 miles northeast of Dallas, at 0536, the flight was given permission to enter the traffic pattern at Love Field, Dallas, with a right-hand turn and instructed to land on Runway 36 The altimeter setting of 29 83 inches and the weather, which included unlimited ceiling, a visibility of 15 miles and a north-northeast wind of 5 mph, were given the flight The captain and the flight engineer conferred regarding returning No 1 engine to service and decided against doing so. The crew then went through the pre-landing cheek The landing lights were turned or and the Plans were lowered to the 20 degree position. The flight turned -flight to final approach when approximately over the Range Station which is 2 2 miles south of the approach end of Runway 36 At this time its altitude was estimated to be 1200 feet AFL 2 by the captain and 800 feet AFL by the first officer At a distance of about 1 1/2 miles from the approach end of the runway, the landing gear was extended. Shortly thereafter the flaps were extended fully, the turn to final placed be aircraft to the left of the runway Accordingly an "S" turn was made to correct the misalignment During this "S" turn the aircraft skidded to Its left, the air speed dropped abruptly and the aircraft settled rapidly. At this point the captain increased power to engines Nos. 2, 3 and 4 in an attempt to maintain control. Control tower operators watching the approach estimated that the aircraft cleared by 75 to 100 feet obstruction lights mounted on 30-foot poles on a power line located 800 feet south of the approach end of the runway. The aircraft continued in a generally northwest direction, across the airport on a heading about 40 degrees to the left of Runway 36, in a tail low attitude. Its air speed continued to fall, its attitude became increasingly nose-high. and a stall developed just prior to striking a hangar and other buildings on the northwest side of the airport. Both pilots and 26 passengers were killed.

While flying by night, the four engine aircraft hit tree tops and crashed in a hilly terrain located near the Mt Saint Helens, about 30 miles east of Kelso. All six crew members were killed.

Due to snow conditions the flight was delayed at Dunkirk for several hours. During this time the crew obtained weather information and had the aircraft serviced with 230 gallons of fuel. Two known attempts to take off from Dunkirk were made, at 0215, and at 0405 but these were discontinued after a short take-off run because of the accumulation of snow on the aircraft. This snow had accumulated during the time the aircraft was on the ground. A special weather forecast requested from New York and delivered to the crew at 0355, predicted that between Dunkirk and Detroit ceilings would be 3,000 to 4,000 feet MSL, visibility seven miles or more, and that there would be icing in the clouds. At 0808, Captain Dede filed with Cleveland Air Route Traffic Control an IFR flight plan which described a route to Detroit by way of Clear Creek, Canada, at an altitude of 4,000 feet, with Cleveland, Ohio, being designated as the alternate airport. Twenty-nine minutes later, at 0837, the flight took off from Dunkirk. There was sufficient fuel aboard to fly three hours and 40 minutes, and the computed elapsed time to Detroit was one hour and 50 minutes. At this time the total gross weight of the aircraft was 27,050 pounds which was 150 pounds above the allowable limit. Routine progress reports were mad, by the flight when over Clear Creek and Windsor, Canada, and at 0954, Detroit Air Route Traffic Control cleared the flight to contact Detroit City Airport Approach Control Instructions were given the flight by Approach Control and Runway 25 was designated as the runway in use. The flight was also advised that the visibility, restricted by snow showers and smoke, was one mile, and that the surface wind was 15 miles per hour from the southwest. The Detroit City Airport tower controller first observed the aircraft one mile east southeast of the airport with its landing gear down, flying on an approximate heading of 300 degrees and at an altitude estimated to be 700 feet above the ground. When the flight was almost over the field, it requested permission to make a left circle of the air port before landing. Clearance to do this was granted and again the flight was instructed to land on Runway 25. The flight passed directly over the airport, turned left and then flew on an easterly heading until it was approximately three quarters of a mile east of the approach end of the runway. Here it was seen to make a steep left turn and change direction approximately 180 degrees. Although the aircraft straightened out from this turn, it continued to lose altitude until it struck the chimney of a house in a residential district of Detroit approximately 3,200 feet east of the airport. The aircraft then struck and demolished a second house approximately 45 feet west of the first house. Fire developed which partially destroyed the aircraft. Both pilots and one person on the ground were killed.

The Boeing B-29-70-BW Superfortress registered 44-69939 was carrying a crew of 11 and was flying at an altitude of 26,000 feet. A second Boeing B-29-50-MO Superfortress registered 44-86364 was carrying a crew of 10 and was flying about 1,000 feet above when one of its engine failed. The aircraft lost height, cut the path of the first B-29 and both aircraft collided at FL260. Out of control, both aircraft dove into the ground and during the dive, two crew members in the first B-29 and one crewman in the second B-29 were able to bail out before both aircraft crashed in a prairie located some 11 miles northwest of Stockton. The three crewmen who were able to bail out were found unhurt while all 18 other occupants in both aircraft were killed.

En route, the aircraft suffered an engine failure and the pilot attempted an emergency landing when the aircraft crash landed in a field located in Mikkalo. A crew member was killed while six other occupants were injured.

The aircraft departed from the North Philadelphia Airport, Philadelphia, Pennsylvania, at 1846, November 4, 1949, for Cleveland. A flight plan was then filed with Philadelphia ATC which specified that the flight proceed from Philadelphia to Allentown according to Visual Flight Rules, and from Allentown to Cleveland according to Instrument Flight Rules at a cruising altitude of 4,000 feet Mansfield, Ohio, was designated as the alternate airport. At the time of takeoff, the aircraft carried 3,000 pounds of fuel and 4,878 pounds of cargo, Total aircraft weight was 24,800 pounds which was within the allowable limit, and the load was so distributed that the aircraft's center of gravity was within the certificated limits. The flight was routine until it reported over Youngstown, Ohio, at 2100, at which time a new flight plan was filed with Cleveland ATC because the Cleveland weather was below the authorized landing minimums and also because freezing rain was forecast at the time of the flight's arrival. The destination was changed to Akron, and Toledo Ohio, was designated as the alternate. At 2114 the flight reported to the Akron-Canton Tower estimating arrival over the Akron Range Station at 2117 at 4,500 feet and the tower issued approach clearance. At 2118 the flight reported over the Akron Range Station Five minutes later, at 2123, the flight reported outbound at 2,500 feet over the outer marker, 4 3 miles south of Runway 36. The tower, at 2128, transmitted to the flight the 2125 Akron-Canton weather as follows. At 2132, the flight reported inbound at 2,500 feet over the outer marker and was cleared to land on Runway 36. This was the last radio contact with the flight Approximately two minutes later the aircraft crashed south of the airport. The wreckage was found 3,250 feet south of the runway 36 threshold and 880 feet east of the center line. All three crew members were killed.
Crew:
James R. Harrington, pilot,
John E. Franklin, copilot,
Robert S. Yarano, crew chief.

Shortly after takeoff from Barksdale AFB, while in initial climb, the crew encountered engine problems. The captain elected to make an emergency landing and reduced his altitude. The airplane crash landed in a field and hit a cotton picker before coming to rest. While all nine crew members were unhurt, the aircraft was written off and the cotton picker was killed.
