Some accidents are burned into memory even decades after they happened. The sinking of the Titanic, the explosion of the Hindenburg, the accident at Tenerife, and the Challenger crash all bring back remembrances of unforgettable tragedies. “The day the music died,” wrote singer/songwriter Don McLean for his hit song, American Pie, in 1971 commemorated the loss of singer Buddy Holly in an aircraft accident. Charles Hardin Holley, better known as Buddy Holly, was and remains one of the giants in the music business. His may be the most-discussed pop music star aircraft accident in history. The impact on the music world and millions of fans still affects the public perception of general aviation two generations of pilots later. His life and death inspired numerous books, movies, and songs.
To say Holly was a star is an understatement. He has been described as, the single most influential creative force in early rock and roll. His style has influenced countless musicians, including The Beatles, The Rolling Stones, and Bob Dylan. He exerted such a profound impact on popular music that Rolling Stone magazine ranked Holly number 13 on its list of the 100 greatest artists of all time.
He was only 22 at the time of his death, and yet his songwriting was so prolific that new albums and singles were released years after his passing. The story of his accident and others like it has been written many times—the outcomes don’t change.
In the early morning of February 3, 1959, Holly and two other rising stars, Ritchie Valens and J.P. Richardson (the Big Bopper), who were touring the country, had just finished a gig in Clear Lake, Iowa. They were scheduled to appear in Moorhead, Minnesota, that night but, because of bus trouble, the show headliners decided to go on to Moorhead by air. The group chartered a Beech Bonanza at the Mason City, Iowa, airport to fly to Fargo, the nearest airport to Moorhead.
The Civil Aeronautics Board (CAB), predecessor to the FAA and the NTSB, investigated the accident and the factual information is derived from the report.
Around 5:30 p.m. Central Standard Time the charter pilot went to the Air Traffic Communications Station (ATCS—the equivalent of today’s Flight Service Station and Air Route Traffic Control Center) at the airport administration building, to brief the flight. He was provided current weather for Mason City, Minneapolis; Redwood Falls; Alexandria, Minnesota; and the terminal forecast for Fargo, North Dakota. The briefer advised that all stations reported ceilings of 5,000 feet or better and visibility of 10 miles or above. However, the Fargo terminal forecast indicated the possibility of light snow showers after 2 a.m. and a cold frontal passage about 4 a.m. It all seemed reasonable for a VFR flight.
At 10 p.m. and again at 11:30 p.m. the pilot called ATCS to update weather. All stations had ceilings of 4,200 feet or better with visibility still 10 miles or greater. It was snowing in Minneapolis and the cold front that was previously forecast to pass Fargo at 4 a.m. was now expected to arrive at 2 a.m. At Mason City the ceiling was 6,000 overcast; visibility 15 miles plus; temperature 15 degrees F; dew point 8 degrees; wind south 25 to 32 knots; altimeter setting 29.96 inches.
At 11:55 p.m., the pilot, accompanied by the FBO/charter aircraft owner, a commercial/instrument-rated pilot, again went to ATCS for the latest weather update. With such important passengers on board one couldn’t be too careful. In the half-hour since the pilot had last checked, Mason City was now 5,000 overcast in light snow and the altimeter had dropped to 29.90. The weather was moving.
Holly, Richardson, and Valens arrived at the airport about 12:40 a.m., after the show, stowed their baggage, and boarded the aircraft. Although not noted in the CAB’s report, I speculate the weight and/or balance might have been outside the limits with any kind of fuel load. That would have made the V35 a handful in the turbulence the flight would later encounter.
The pilot stated he would file his VFR flight plan by radio when airborne. Taxiing to the end of Runway 17, the pilot called ATCS for a weather update. En route reports had not changed materially, but Mason City was coming down rapidly: The ceiling was now 3,000, sky obscured; visibility 6 miles, light snow; wind south 20 knots, gusts to 30 knots; altimeter setting 29.85 inches. The front had arrived.
The Bonanza was airborne at 12:55 a.m. and observed to make a left 180-degree turn and climb to approximately 800 feet. It passed east of the airport and turned northwesterly. Throughout most of the flight the aircraft’s tail light was visible to the FBO/charter aircraft owner. About five miles from the airport the light gradually descended and disappeared. When the pilot failed to open his flight plan by radio soon after takeoff, the communicator (controller), at the owner’s request, repeatedly tried to reach him but was unsuccessful. It was approximately 1 a.m.
After reporting that the aircraft was missing at 3:30 a.m., the FBO/charter aircraft owner flew the aircraft’s planned route later that morning. He sighted the aircraft in an open field at 9:35 a.m. All four occupants had been killed, and the aircraft was demolished. The wreckage was covered with about four inches of snow. It’s a given, even today, that accident investigations are usually done in decent weather, half a day later. Note to self—be a little patient with weather, it will get better. Had the group left at 10 that morning, they still would have arrived in plenty of time for the show.
The Bonanza struck the ground in a steep right bank, nose-low attitude at high speed. There was no fire and no evidence of structural or flight control failure. The landing gear was retracted and the engine was producing cruise power at the time of impact. The attitude indicator showed a 90-degree right bank, nose-down attitude. The vertical speed indicator was pegged at a 3,000-feet-per-minute descent.
The pilot, 21 years old, was employed by the FBO as a commercial pilot and flight instructor, and had been with them about a year. He had started flying in October 1954, with 711 hours total time and 128 in Bonanza. He had approximately 52 hours of dual instrument training and had passed the instrument written examination, but he had failed an instrument flight check in March 1958, nine months prior to the accident. His instrument training had been in several aircraft, all equipped with a conventional artificial horizon, but he had no experience with the Sperry attitude gyro that was installed in Bonanza N3794N. These two instruments differ greatly in their pictorial display, and the CAB believed that he would have had difficulty interpreting a completely different display.
The Beech Bonanza, model 35, was manufactured in October 1947 and the engine had only 40 hours since major overhaul. The aircraft was purchased by the FBO in July 1958, and was well equipped for its time with high- and low-frequency radios, a Narco “omnigator” (VOR), a Lear autopilot (recently installed but not operable), and a full panel of instruments used for instrument flying, including a Sperry F3 attitude gyro.
According to the CAB’s report, “The conventional artificial horizon provides a direct reading indication of the bank and pitch attitude of the aircraft which is accurately indicated by a miniature aircraft pictorially displayed against a horizon bar and as if observed from the rear. The Sperry F3 gyro also provides a direct reading indication of the bank and pitch attitude of the aircraft, but its pictorial presentation is achieved by using a stabilized sphere whose free-floating movements behind a miniature aircraft presents pitch information with a sensing exactly opposite from that depicted by the conventional artificial horizon.”
The weather was quite a bit nastier than the briefed surface reports indicated. The surface weather chart for midnight February 3, 1959, showed a cold front extending from northwestern Minnesota through central Nebraska with a secondary cold front through North Dakota. Widespread snow shower activity was indicated in advance of these fronts. Temperatures aloft from Mason City to Fargo were below freezing at all levels with an inversion between 3,000 and 4,000 feet and abundant moisture present at all levels through 12,000 feet. Moderate to heavy icing and precipitation existed in the clouds along the route. Winds aloft below 10,000 feet were reported to be southwest at 30 to 50 knots.
A flash advisory (roughly equivalent to a sigmet) issued by the Weather Bureau at Minneapolis at 11:35 p.m. on February 2, noted, “Flash Advisory No. 5: A band of snow about 100 miles wide at 2335 from extreme northwestern Minnesota, northern North Dakota through Bismarck and south-southwestward through Black Hills of South Dakota with visibility generally below two miles in snow. This area or band moving southeastward about 25 knots. Cold front at 2335 from vicinity Winnipeg through Minot, Williston, moving southeastward 25 to 30 knots with surface winds following front north-northwest with 25 to gusts of 45. Valid until 0335.”
Another flash advisory issued out of Kansas City, Missouri, at 12:15 a.m. on February 3 noted: “Over eastern half of Kansas, ceilings are locally below one thousand feet, visibilities locally two miles or less in freezing drizzle, light snow, and fog. Moderate to locally heavy icing, areas of freezing drizzle and locally moderate icing in clouds below 10,000 feet over eastern portion Nebraska, Kansas, northwest Missouri and most of Iowa. Valid until 0515.”
Neither ATCS briefer mentioned these flash advisories to the pilot indicating the virtual certainty that instrument weather would be encountered.
The CAB report noted that the flash advisories were not conveyed to the pilot. The weather briefing consisted solely of reading current weather at en route terminal and terminal forecasts for the destination. Failure to “draw these advisories to the attention of the pilot and to emphasize their importance could readily lead the pilot to underestimate the severity of the weather situation.”
The FBO owner said, he “had confidence in the pilot and relied entirely on his operational judgment with respect to the planning and conduct of the flight.” That confidence was sadly misplaced. It happens too often that enthusiasm and a strong desire to complete a flight overcome what little experience/judgment a new pilot has. Sincerity, enthusiasm, and desire to please should never take a back seat to suspicious, skeptical contingency planning.
The CAB noted that with the obviously deteriorating weather at Mason City which could be seen by all, and the fact that the charter company was “certificated to fly in visual flight rules only…together with the pilot’s unproved ability to fly by instruments, made the decision to go…most imprudent.” That the pilot checked the weather so many times and that the owner went with him and then watched the flight depart shows that both of them probably had some serious misgivings. Note to self: Listen to that inner voice—it’s usually right!
The CAB’s assessment was that shortly after takeoff the flight entered complete darkness with no horizon, falling snow, and moderate turbulence from the high winds. This required flight by reference to instruments.
The pilot’s unfamiliarity with the Sperry F3 gyro, noted above, because of its unique presentation, likely caused spatial disorientation.
“The board determines that the probable cause of this accident was the pilot’s unwise decision to embark on a flight which would necessitate flying solely by instruments when he was not properly certificated or qualified to do so. Contributing factors were serious deficiencies in the weather briefing, and the pilot’s unfamiliarity with the instrument which determines the attitude of the aircraft.”
This report could have been written last month, but it was a half-century ago. If the weather is bad where you are, despite a decent forecast, the weather is bad. Period. The board’s commentary: “This accident, like so many before it, was caused by the pilot’s decision to undertake a flight in which the likelihood of encountering instrument conditions existed, in the mistaken belief that he could cope with en route instrument weather conditions, without having the necessary familiarization with the instruments in the aircraft and without being properly certificated to fly solely by instruments.”
We may be the only beings who can learn from past mistakes and so often fail to do so. The lesson should not fade away.
