The controller was publicly blamed for the accident by both airlines and was vilified in the press. The thunderhead over the Grand Canyon was already massive by 10:30 on the morning of June 30, with its top reaching above 25,000 feet. It called for Mainliner Vancouver to proceed to the Palm Springs Intersection, then direct to the CAA communications station at Needles, Calif.; Painted Desert, Ariz.; Durango, Colo.; Pueblo, Colo.; St. Joseph, Mo. Despite the considerable difficulties, CAB experts were able to determine with a remarkable degree of certainty what had transpired and, in their report, issued the following statement as probable cause for the accident: In the report, weather and the airworthiness of the two planes were thought to have played no role in the accident. The Connie gathered speed and lifted off, airborne at 9:01—31 minutes late, a delay that would prove fatal. Four months before the crash, President Dwight D. Eisenhower appointed World War I ace Edward P. Curtis as his special assistant for aviation facilities planning. The separation of the empennage from the Constellation resulted in an immediate loss of control and the aircraft went into a near-vertical terminal velocity dive. Walter Cronkite, reporter and news anchor for CBS News; dubbed "The Most Trusted Man in America.". William III, Prince of Orange, later King of England, Scotland and Ireland. Conclusions reached by investigators of this accident will change aviation forever. Following more congressional hearings, the Federal Aviation Act of 1958 was passed into law, dissolving the CAA and creating the Federal Aviation Agency (FAA, later renamed Federal Aviation Administration). “1,000 on Top” Due to the substantial loss of life and the chain of events that led to it, the Grand Canyon tragedy was extensively covered by the press, both in the USA and abroad. It would not be until the late 1970s that human factors would be as thoroughly investigated as technical matters following aerial mishaps.[11]. Keep track of everything you watch; tell your friends. According to TWA and United, however, the flight crews had not broken any company rules. Meanwhile Captain Robert F. Shirley, pi­loting United Airlines Flight 718, a DC-7 with 58 passengers and crew aboard bound from Los Angeles to Chicago, was also dodging the rainstorm. The report says their flight plan was Needles direct to Durango, but it's unclear what "Durango" means. The "Palm Springs" intersection was at about 33.92N 116.28W. The collision of two airliners above the Grand Canyon in 1956—at the time the deadliest American air accident, resulting in the loss of 128 passengers and crew—had a profound effect on the aviation industry as well as the United States as a whole. An FBI forensic team could identify only three of the 70 passengers and crew members on the TWA airliner, while half of those aboard the United flight were identified. Hunter's finely detailed gouache painting first appeared in LIFE's April 29, 1957 issue and was subsequently included in David Gero's 1996 edition of Aviation Disasters II. Curtis also recommended superseding the Civil Aeronautics Adminis­tration and the Civil Aeronautics Board with a new federal aviation agency to streamline air operations, modernize ATC technology and make and enforce safety rules. Grand Canyon Mid-Air Collision June 30, 1956. However, upon hearing of the missing airliners, Palen decided that what he had seen might have been smoke from a post-crash fire. After a period of time had elapsed in which neither flight had reported a current position, the aircraft were declared to be missing and search and rescue procedures started. This episode was tough to watch but the information gleaned from the investigation is appreciated. The Super Constellation was powered by four Wright R-3350-DA3 turbo compound radial engines, each developing 3,250 hp. Owen/Time Life Pictures/Getty Images). As testified by Charles Carmody (the then-assistant ATC director) during the investigation, neither flight was legally under the control of ATC when they collided, as both were "off airways." But taking the system as it then existed and extending its authority to control all aircraft at all times in U.S. airspace was simply not possible. This feature originally appeared in the March 2011 issue of Aviation History. Both aircraft were due to report in when they reached the Painted Desert line of position east of the Grand Canyon.

Both crews had estimated that they would arrive somewhere along the Painted Desert line at about 10:31 AM Pacific time. But simply enlarging cockpit windows was clearly not the complete answer to increased aviation safety. (AP Photo/David F. Smith) Burned area shows where a UAL DC-7 crashed here on Saturday June 30 after an apparent mid-air collision with a TWA Constellation, killing a total of 128 persons. But before getting a response, Gandy called Daggett again and made another request, telling the TWA radioman that if his request for 21,000 was not approved, he wanted a VFR clearance of “1,000 on top”—which would require Flight 2 to stay 1,000 feet above any clouds and not fly through them. A number of years elapsed following this accident before most of the wreckage was removed from the canyon. Compared to the Connie’s curved lines, the DC-7, Mainliner Vancouver, was all straight-line power. [2] The DC-7, although still operating under IFR, was now "off airways"-that is, flying in uncontrolled airspace. Later that day, a U.S. Army search-and-rescue helicopter landed at the Constellation crash site. Even before the Grand Canyon accident there had been pressure to improve air safety in the United States. Jeff Probst, game show host and executive producer, best known as the host of the US version the reality show Survivor. Captain Gandy, his first officer James Ritner and flight engineer Forrest Breyfogle were scheduled to depart for Kansas City at 8:30 in Star of the Seine, designated as Flight 2. The wreckage was first seen late in the day near the confluence of the Colorado and Little Colorado Rivers by Henry and Palen Hudgin, two brothers who operated Grand Canyon Airlines, a small air taxi service. (bracketed words were inferred by investigators from the context and circumstances in which they were uttered).[10]. This episode entitled "Air Emrgency: Grand Canyon Collision",actor Tony Nappa played my uncle, Gerard Fiore, 1916-1956. Add the first question. The story of the disaster was featured on the eighth season of Canadian National Geographic Channel show Mayday (known as Air Emergency in the US, Mayday in Ireland and Air Crash Investigation in the UK and the rest of world). L.A. Center advised Flight 2 that it was unable to approve the requested altitude because of traffic—that traffic being United 718, which at 9:21 was climbing to its approved IFR altitude of 21,000 feet. [8] Post-crash analysis determined that the United DC-7 was banked to the right and pitched down at the time of the collision, suggesting that one or possibly both of the United pilots saw the TWA Constellation seconds before impact and that evasive action was attempted.[9]. But the most important aspect of 1,000 on top was that as far as air traffic control was concerned, it allowed Gandy to fly at whatever altitude he wished, right up to the Connie’s service ceiling of 24,000 feet. The following day, July 1, Palen Hudgin returned to the area and spotted a field of burned wreckage that marked Star of the Seine’s demise in a draw on the northeast slope of Temple Butte. I think he wants a thousand on top.” L.A. Center then granted that request: “ATC clears TWA 2, maintain at least one thousand on top. Their flight engineer was Girardo Fiore, 39, who had started as a mechanic and worked his way up to a seat in the cockpit. The morning was clear and sunny when a deHavilland DHC-6-300 Twin Otter "Vistaliner" (N76GC) operated by Grand Canyon Airlines departed for it's hour long air tour. Thanks to modern airliners with transcontinental range like the Con­stellation, Americans were flying more than ever before. Just three minutes after the TWA flight took off, United Airlines Flight 718, nonstop to Chicago, lifted clear of LAX’s runway 25L. Thanks to the Civil Aeronautics Board’s accident investigation report, we can piece together how and why TWA Flight 2, a Lockheed Super Constellation, and United Airlines Flight 718, a Douglas DC-7, collided on the morning of June 30, 1956, then crashed deep inside the canyon, a little over a mile apart. Los Angeles International Airport bustled with activity when the TWA flight departed that morning. As related by Susan Smith-Hunter, Mel Hunter's widow. The Curtis report, delivered to Eisenhower in July 1957, argued for positive control of all high-altitude flights using radar.

The painting showed the DC-7 below the Constellation, with the former's number one engine beneath the latter's fuselage, which agreed with the CAB technical findings.[16]. Re­membering the smoke he had seen, he flew with his brother to the Little Colorado, where they spotted the Connie’s tail assembly far below them. The company radio would report airplane positions to CAA flight advisory stations and air route traffic control centers. Simultaneously, the propeller on the DC-7's left outboard (number one) engine chopped a series of gashes into the bottom of the Constellation's fuselage. Flight 718 reported at 9:58 that it was over Needles at 21,000 feet, and estimated it would cross the Painted Desert line of position in Arizona at 10:31. The only immediate indication of trouble was when United company radio operators in Salt Lake City and San Francisco heard a garbled transmission from flight 718, the last from either aircraft. But for the American flying public the results of that investigation raised an important question: How had the U.S. air traffic control system allowed two modern airliners to collide? In his novel Skeleton Man (2004), Tony Hillerman uses this event as the backdrop to the plotted events of his story. Also, there were no credible witnesses to the collision itself or the subsequent crashes. That was the last broadcast from either aircraft until 10:31, when Flight 718 transmitted, “…we’re going in.”, Arrows mark the spots where TWA’s Constellation and United’s DC-7 crashed in the Grand Canyon after their midair rendezvous, killing all 128 people aboard both planes.
