Circumstances:
This flight was designated by West Coast Airlines, Inc., (WCA) as Pilot Training Flight No. 703. It was for the purpose of rating a company DC-3 captain for F-27 aircraft. N 2703 arrived at Salt Lake City Municipal Airport January 17, 1963, at 1431 1 as West Coast Flight 752 from Seattle, Washington, with stops at Yakima, Pasco, Walla Walla, all in Washington; Lewiston, Montana; and Boise and Twin Falls, both in Idaho. The flight had been uneventful and there were no carryover discrepancies entered in the aircraft's flight log. After completion of turnaround servicing, N 2703 departed the West Coast Airlines ramp at approximately 1506 with Company Cheek Pilot Instructor William Harvey Lockwood, Trainee Captain Elmer J. Cook, and FAA Carrier Inspector Buell Z. Davis aboard. A flight plan was prepared and signed by Captain Lockwood. It listed Elmer J. Cook as the first officer, FAA Inspector Buell Z. Davis as a crew member, and specified that the flight would be in the local area, under VFR conditions, and of 1 hour and 30 minutes duration. At departure Captain Cook occupied the left pilot seat, Captain Lockwood the right pilot seat, and Inspector Davis the observer's (jump) seat. The aircraft carried approximately 3,500 pounds of fuel which was ample for the intended flight. The aircraft's computed gross weight was 28,310 pounds, approximately 7,000 pounds less than maximum allowable for takeoff, and the center of gravity was within prescribed limit. Flight 703 took of f at 1510 and remained in the traffic pattern for a practice landing which was made at 1517. At 1522, Flight 703 made a second takeoff and was last observed three miles south of the airport by the local controller in the tower. The tower clearance for this takeoff was the last radio contact with the flight. The next known sighting of Flight 703 was from the air by the crew of Western Airlines Flight No. 38. At 1531 they observed it at an estimated altitude of 8,000 feet mean sea level (m.s.l.) descending to an estimated altitude of 7,000 feet m.s.l. with the left propeller feathered. It was headed southeasterly, and in the vicinity of the southern tip of Antelope Island in Great Salt Lake, some 10 miles west-northwest of the airport. Several minutes later, the ground controller in the Salt Lake City Tower observed Flight 703 for a few minutes. He saw it approaching the airport from the west at an estimated altitude of 8,000 feet above the ground. It appeared to be flying level as it came approximately over him, continuing a few miles to the east and over Salt Lake City. It then made a right turn to a west-northwesterly heading and continued in that direction until the controller discontinued watching it at a point approximately five miles west of the airport. He did not notice anything unusual about the aircraft's appearance or performance. The next observation of Flight 703 was by a motorist near the southeastern shore of the Great Salt Lake who saw it at an estimated 3,000 feet above the ground descending. He estimated the time of his initial observation to be 1550. The aircraft appeared to be on a northwesterly heading making a normal descent considerate west of the Salt Lake City Airport and continued descent until it appeared "to actually go into the lake itself." He did not see any splash; his position was about six miles from where the wreckage was later found. The official U.S. Weather Bureau observation at Salt Lake City Municipal Airport at 1555 on the day of the accident was: Ceiling estimated 12,000 feet broken, high overcast, visibility 12 miles, temperature 34 degrees F., dewpoint 2 degrees F., wind from south-southwest at 5 knots, altimeter setting 30.05, smoky, snow showers of unknown intensity east. Weather conditions were not appreciably different an hour earlier nor an hour later. At 1700, the Salt Lake City Flight Service Station (FSS) received a request from the Salt Lake City Air Route Traffic Control Center (ARTCC) to initiate a call to Flight 703 on all available frequencies. There was no reply from Flight 703 to these calls. At 1758 the Salt Lake City FSS received information from the Salt Lake City ARTCC that West Coast Flight 703 was overdue and unreported. On January 18, 1963, at approximately 1140, one body and aircraft debris was seen floating in Great Salt Lake. This floating debris was 10.4 nautical miles to the Salt Lake City Very High Frequency Omni Directional Range (VOR) or the 248 de radial. Early next morning the other two bodies were sighted and all three were recovered from the lake.
Probable cause:
The probable cause of the accident was the crew's lack of vigilance, for undetermined reasons, in not checking a simulated emergency descent before striking the water.

Circumstances:
The crew was performing a flight from Sioux City to Ogden-Hill AFB, Utah. Upon arrival, the pilots mistook Ogden-Hinckley Municipal Airport for the nearly Ogden-Hill Airbase. After touchdown on a too short runway for this kind of aircraft, the heavy bomber overran, hit a 10-foot wide drainage ditch, crossed a highway and came to rest in flames. A crew member, James A. Gerwick, was killed, while six other occupants were injured. The aircraft was destroyed.
Probable cause:
Crew error while landing on the wrong airport.

Circumstances:
Flight 608 departed Los Angeles, California, at 1023 with its destination Chicago, Illinois, to cruise at 19,000 feet according to visual flight rules. Routine position reports were made over Fontana, Daggett and Silver Lake, California; Las Vegas, Nevada; and Saint George, Utah. During the latter report, the flight indicated that it estimated passing over Bryce Canyon, Utah, at 1222. At 1221 Flight 608 reported that a fire had been detected in the baggage compartment which the crew was unable to extinguish. The report added that the cabin was filled with smoke and that the flight was attempting to make an emergency-landing at Bryce Canyon Airport. Shortly thereafter the flight again reported that the “tail is going out--we may get down and we may not.” At 1226 another transmission was received from the flight indicating that it was going into the “best place” available. One minute later the flight reported “we may make it--approaching a strip.” No further contact was had from the flight. Witnesses who observed the aircraft as it was approaching Bryce Canyon from approximately 20 miles southwest first observed what appeared to be white smoke streaming from the aircraft, followed later by dense black smoke. The first witnesses who observed fire in the bottom of the aircraft at approximately the center-section were located approximately 15 miles south of Bryce Canyon. Until shortly before the moment of impact, the aircraft appeared to be under normal control; however, no witnesses were located who observed the crash.
Probable cause:
The Board determines that the probable cause of this accident was the combustion of gasoline which had entered the cabin heater air intake scoop from the No. 3 alternate tank vent due to inadvertent overflow during the transfer of fuel from the No. 4 alternate tank. Contributing factors were the improper location of the No. 3 alternate tank air vent outlet and the lack of instructions provided DC-6 flight crews concerning hazards associated with fuel transfer.
The failure of the manufacturer and the Civil Aeronautics Administration to exercise full caution in the analysis of the fuel system of the DC-6 relative to proper location of fuel tank vents to provide non-hazardous location for fuel drainage, as required by existing regulations, and the insufficient attentiveness on the part of the manufacturer, the Civil Aeronautics Administration, and the air carriers to the procedures of fuel management employed by pilots operating DC-6 aircraft, were contributing factors.

Circumstances:
A formation of five Consolidated B-24E Liberator was on its way from Wendover AFB to Pocatello, Idaho. While cruising at an altitude of 11,100 feet, the Liberator registered 42-7183 that was in the third position was left behind so its captain increased power to regain its position in the formation. Doing so, the tail of the 42-7183 hit the left wing of the 42-7408. On impact, the number one engine of 42-7408 was sheared off and both aircraft went out of control, dove into the ground and crashed in a huge explosion. All 25 occupants on both aircraft were killed.

Probable cause:
According to officials, the pilot of the aircraft registered 42-7183 bears full responsibility for this tragedy because he did not comply with basic rules of discipline during a training flight. However, investigators point out that the massive presence of ice in the region remains a contributing factor to the accident in the sense that aircraft performances were reduced.
