I was 17 years old in 1969. It was the year of Woodstock. The Beatles released their album Abbey Road. Oh, and in July humans had first set foot upon the moon. So I could be forgiven for
thinking the world was on a steady if stumbling progression to a more perfect union. And then, just after noon on Tuesday, 9 September, Allegheny Airlines flight #853 (above) lifted her wheels off the runway at Boston’s Logan Airport and clawed her way into the sky.
At about the same time, some 818 miles to the west southwest, 34 year old Robert William Carey (above) was just leaving his job at William Steck Plumbing, in Indianapolis, Indiana. He'd been working since eight that morning, but now he was headed home, to share lunch with his wife Lorraine and their four children who were still at home, They had two other children, Thomas and Michael, who were now in school.
Driving home Bob was disappointed to see the light northwestern breeze had drawn a pretty solid cumulus ceiling (above) down to 1,400 feet. This meant he would likely not be able to get in another solo cross country fight before his Private Pilot Check Out ride, scheduled for next week. It was the only remaining hurdle before getting his pilot's license. His instructor described Bob as big man with a ruddy complexion, with "a very happy personality".
Fifty-four years earlier, in 1914, Donald Willis Douglas had been the first person to receive a Masters degree in Aeronautical Engineering from M.I.T. His legendary career included building 16,000 of the legendary Douglas Commercial Three (or DC-3) twin engine propeller driven transport and passenger planes. The final aircraft Donald Douglas built was the first jet powered passenger plane to enter service in the U.S., the DC-8 (above). This put him in direct competition with the rival Boeing Aircraft's glitzy 707.
In 1957 Donald Willis Douglas Junior (above) became chairman of Douglas Aircraft. Looking for a new market, he decided to bring the jet engine's advantages of cheap fuel, higher speed and altitude producing smoother flights to mid and short range passenger routes, by building a new passenger jet.
And he decided to build the new plane by enlarging Douglas's facilities at Long Beach, California (above). Shortly thereafter the company merged with McDonnell aircraft.
It was a short to mid-range passenger jet, unglamorous, uncomplicated and so reliable that some 2,400 were eventually produced at the Long Beach plant. The DC-9-type 30 had a swept wingspan of 93 feet, and was 133 feet long from nose to the swept fins of her high “T” tail. Her two rear mounted Pratt & Whitney JTD8D-7 turbofan engines could propel her through the air at over 500 MPH above 30,000 feet for over 2,000 miles, while allowing her to use the shorter runways at smaller airports.
DC-9 airframe number N (designating the United States) 988FJ rolled off the Long Beach production lines in August of 1968, and as of Tuesday, 9 September, 1969, had only 3,170 hours on it.
Allegheny flight #853 was commanded by 47 year old pilot Captain James Elrod.(above). He had 900 hours at the controls of DC-9’s, and 23,800 total hours as a pilot. He lived in Plainfield, Indiana, almost within sight of the Indianapolis airport, with his wife Marge and their three children.
His first officer and co-pilot was 26 year old bachelor William Heckendorn (above), who had 650 hours at the controls of the twin engine jet, and 2,980 flight hours in total. Like many care free bachelors William had just bought a new 1968 Corvette convertible, But William also had just conservatively invested in a service station with his brother in their home town of Newville, Pennsylvania, and he was currently dating Allegheny Stewardess Margi Barletta.
Allegheny had started in 1939 as regional airline based in Pittsburg, and by the1968 serviced Atlantic City, Baltimore, New York City, Philadelphia, Washington, D.C., Cincinnati , Chicago, St. Louis, Indianapolis and many small towns in between. The airline was always profitable because it received subsidies for providing service to all those smaller cities. Thus the airline business in a regulated airline industry.
Senior "Stew", 29 year old Patricia Ann Perry (not above) had been born in Moorseville, Indiana and was described as "a very bright and pretty brunette". She now made her home in Massachusetts, with her fiance', who was an Allegheny pilot. In fact he was supposed to have been deadheading on this very flight before being rescheduled. The pair were be married in a week.
Working the narrow cabin with Patricia was 31 year old Barbara Louis Petrucick, who was based in Boston. And deadheading was 20 year old off duty Stewardess Linda Marlene Smalley, who had just attended her brother's wedding in Maine.
About an hour and forty minutes later. Flight #853 landed at Friendship Airport (above), and taxied up to the terminal. There were few "jet bridges" in use in 1968 and passengers boarded and de-boarded their aircraft via stairs directly to the tarmac. (below)
At Baltimore 16 additional passengers boarded the DC-9. The flight then quickly took off again, for the 424 mile, 90 minute flight to Cincinnati Airport ( designated CVG).
Back in Indianapolis, by 1:00pm on Tuesday, 9 September, 1969, Bob Carey was pleased to see the ceiling had climbed to 2,900 feet and was broken enough (about 8/10ths) to make his training flight to Purdue airport practical. He kissed Lorraine goodbye, climbed into the family station wagon and headed for McCordsville (later renamed Brookside) airpark. He got there a little after 2:00pm.
McCordsville Airpark (above) was about 25 miles north/northwest of Indianapolis. Since 1964 it had been owned by the Forth family, where they sold, rented and serviced aircraft as well as providing ground instruction to student pilots. The field boasted a 3,100 foot paved runway (#18/36) and a 3,152 foot turf runway (#6/24), as well as a parking ramp and 2 hangers on the east side of the field. On all airports, the runways designations referred to the compass headings, rounding to the nearest 10 degrees, which always produces a number between 1 and 36. Which of the two numbers apply depends upon which direction you are approaching from.
Sitting on the tarmac was a year old Piper Aircraft Corporation two seat single engine PA-28 Cherokee (above), tail #28-24730, leased by Forth Corporation since 13 August, 1968, at $208. 78 a month. This was the aircraft Bob Carey had been learning to fly in for the past year, and the one he wanted to use for today's flight. Bob's instructor, Robert Kiesel, was not at the field this afternoon, Instead it was chief flight instructor for Forth, Robert Rice, who signed Bob off for his final flight. And it was Rice encouraged Bob Carey to change his flight plan.
The clouds were clearing from the south, and storms were possible around Lafayette that afternoon. So, following Robert Rice's advice, Bob Carey decided to instead fly 40 miles south to Bakalar Air Force Base, 4 miles northeast of Columbus, Indiana, and then return to McChordsville.
Allegheny Flight #853 landed at the Cincinnati/Northern Kentucky airport (above) about 2:40 pm EST,
It was then supposed to leave at about 2:57pm. But an Allegheny ticket agent decided the hold the DC-9 on the ground so an additional 38 passengers could board. These folks were supposed to have connected with TWA flight 69, flying from New York City and arriving in Cincinnati at 2:45pm. However when that TWA flight was delayed, an Allegheny ticket agent decided to hold hold #853 on the tarmac so the TWA passengers could make the connection. That agent struggled with his decision for the rest of his life.
The Allegheny DC-9, now crowded with 82 passengers and a crew of four, lifted off at about 3:15pm. Air Traffic Control vectored Allegheny #485 to airway V-97, at 10,000 feet. Half an hour later, TWA flight #69 landed in Cincinnati, to collect the remaining 26 passengers. They then flew safely to Indianapolis, St. Louis and then on to Los Angeles.
At about the same time Bob Carey was filing his new flight plan by fax with the FAA at Weir Cook Airport, Indianapolis. Bob lifted off from McCordville airport at 3:11pm. Following Visual Flight Rules he would be flying at 2,500 feet, heading south at 150 miles per hour. At 3:21pm he contacted Indianapolis Flight Service, notifying them he had departed McChordsville. The cloud cover at Bakalar airfield was 2,900 feet and broken. Not having a transponder in his Cherokee, Bob Carey's aircraft would be too small and too far away to appear on the radar screens of Indianapolis Approach.
Captain Jim Ellrod was at the controls of Allegheny Flight 485, as it left Cincinnati, on a heading of 306 degrees, flying toward Shelbyville, Indiana (above), a distance of 64 nautical miles at 400 miles per hour. It was anticipated that Flight 853 would roll up to the terminal at Indianapolis at 3:50 pm.
First Officer William Heckendorn was monitoring the gauges and handling communications. At 3:22pm Indianapolis Air Route Traffic Control Center (ARTCC) advised the DC-9, "Allegheny eight fifty three is in radar contact, cross Shelbyville at and maintain six thousand and your position is now thirty-two miles...southeast of Shelbyvlle." 
Three minutes later, at 3:25pm, Allegany Flight #853 over flew the Shelbyville VOS, First Officer Heckendorn informed Approach Control that his flight was leaving 10,000 feet for 6,000, as instructed. The controller responded two minutes later, "Allegheny eight five three, squawk indent heading two eight zero radar vector visual approach three one left". Jim Ellrod now lowered the DC-9's speed to about 200 miles per hour.
William Heckendorn now entered the number 208 in the transponder (above), and that identification (or ident number) now appeared on the Approach Control radar screen next to the "blip" representing the DC-9, thus providing the operators with a positive I.D, for which blip was Allegheny Flight #853.
Merrill McCammack was doing the work of two controllers on this day, but that was within FAA guidelines. As a veteran controller he had was not facing any especially difficult problems. His radar equipment could display targets out to fifty miles, but McCammack had set the display for a thirty mile range. The antenna rotated at fifteen revolutions per minute, thus providing the controller with a completely updated radar picture every four seconds.
At 3:29pm and 13 seconds Co-pilot William Heckendorn radioed, "Out of thirty-five for twenty-five" As he heard that response, Controller McCammack briefly turned his attention to Allegheny Flight #820, which was also inbound to Indianapolis but approaching from the west. Some 10 seconds later, when he returned his attention to Flight #853, that blip had disappeared from his radar screen.
Just about 3:30pm, that Tuesday afternoon, a knot of parents and grandparents, were sharing small talk on the entrance road to the Shady Oaks Trailer Park, on the outskirts of Fairland, Indiana (above) - 10 miles northwest of Shelbyville. They were slightly anxious because the school bus carrying their children home from the day at school was just about to pull to a stop on North London Road.
When the jet, coming from the southeast, slipped below the broken cloud cover, the sudden whine of it's engines - made louder by the overcast - drew the immediate attention of all 8 people. Looking up they all saw a smaller plane approaching from the north moving straight toward the larger jet. Neither plane made any attempt to avoid the collision. One young woman shouted to her husband, "I think they're going to hit!" 
At 3:29pm, and 15 and 2 tenths of a second the top right front of the vertical stabilizer, just below the twin horizontal stabilizers (above) sliced through the root of the Piper's left wing, inches from Bob Carey's seat, scraping across Bob's head as it decapitated the Cherokee at a 45° angle. As the author of a web site devoted to the crash wrote, Bob Carey "...died instantly, without even being able to have the comfort of a last thought for the wife and children he loved so much."
The left wing of the Cherokee, ripped from it's connections, fluttered away toward the ground. The propeller continued to turn for a few tenths of a second, making cuts on the underside of the DC-9's right horizontal stabilizer. Then momentum carried the right wing, most of the fuselage and most of the cockpit forward, scrapping along the bottom of the jet's right horizontal stabilizer.
The forward motion of the Allegheny Jet cancelled the energy of the Cherokee and what was left of the Piper fluttered to the ground almost directly under the impact point. Jim Carey's was still strapped into his seat and was the only body which was found intact. His death was instantaneous. But that appearance disguised his internal injuries, as his body had sustained tens of thousands of "Gs", over a few seconds.
The victims onboard the DC-9 are not as lucky. Not one of 88 souls on board Flight #853 was even injured in the collision. However the entire vertical tail assembly (above) had been ripped from the rest of the airframe, breaking just aft of the pressure tube containing the passenger cabin and cockpit. One second after the impact, at 3:29pm and 16 seconds, according to the Cockpit Voice Recording, a warning horn sounded, to alert the pilots they were below stall speed and should lower their landing gear. One second later the Stall Vibration warning began sounding.
A second after that, at 3:29pm and 17 seconds, the landing gear warning horn stopped. Pilot Jim Elrod was heard to say, "..(the) tail must be".... First Officer Heckendorn blurted out, "What did you hit up there?"
With the tail gone, the abrupt shift in the center of gravity caused the airframe to nose downward, yaw to the right and roll to the left, all at the same instant. The passenger jet was now inverted and the engines were driving the airframe in quick shallow dive 2,500 feet toward the earth, The last words heard on the CVR were typical of fatal crashes - "Oh, shit!" It was exactly 3:29 pm and 27 seconds, on Tuesday, 9 September, 1969.
Passengers and crew of Allegheny Flight #853 were all alive 11 seconds after impact, when at about 400 miles per hour, what was left of the DC-9 pancaked into a soy bean field, 100 yards from a mobile home park.
The wings fractured and scattered. Their kerosene fuel in the wing tanks was so dispersed as an aerosol that no fire resulted. Everything contained within the pressure hull, including the tube itself, shattered. Parts of seats, flooring, overhead bins, luggage and passengers were thrown out from the point of impact, generally in the direction of motion, to the northwest.
The pilots and some of the passengers were technically alive after the crash, but despite myths, no one survived for more than a few moments. Eighty-eight human beings and about four million dollars worth of equipment ($23.5 million in 2007) had been destroyed in 13 seconds. It was the 19th mid-air collision in the year 1969.
Back in the Approach Control at Weir Cook Airport, Controller Merrill T. McCammack was not particularly concerned when the northbound DC-9 dropped off this radar screen. because, "...it's not unusual to miss a target for two or three sweeps." It was not until 3:30pm and 52 seconds before he asked, "Allegheny eight five three, what is your altitude?" He admitted later, "I didn't necessarily care...what his altitude was...I wanted to hear his voice." But there was no response.
The school bus sat across the access road to the Shady Oaks trailer park (above) while lighter machine and body parts dropped around it. The bus driver ordered the children to stay in their seats, while he moved several body parts from their path so the children could walk home. Shaken himself, he then returned to finish his route.
At 3:40pm, when Controller Merrill McCammack called to notify the Indiana State Police of the possible loss of a passenger jet, they were able to inform him that not only that it had crashed, but where it had come down.
On 15 July, 1970 the National Transportation Safety Board, charged with investigating aviation accidents, urged the Federal Aviation Administration change it's regulations to prevent similar future disasters. “The board determines the probable cause of this accident to be the deficiencies in the collision avoidance capability of the Air Traffic Control system...in a terminal area wherein there was mixed instrument fight rules (IFR) and visual flight rules (VFR)…include(ing) the inadequacy of the see-and-avoid concept under circumstances of this case; the technical limitations of radar in detecting all aircraft; and the absence of ….adequate separation of …mixed traffic in terminal areas.”
And yet, on 31 August, 1986, 18 years after Allegheny Flight #853, in clear skies this time, another DC-9, Aero Mexico Flight #448, collided in midair with another Piper Cherokee PA-28, this time over Cerritos, California, killing another 85 people, including 15 on the ground. This time part of the blame was laid on the Piper pilot who was unfamiliar with the area and had entered restricted airspace without clearance. But the secondary fault was again laid on “…limitations of the see and avoid concept to ensure traffic separation…”. 
The Shady Oaks Trailer Park is still on North London Road, although it is now called Creekside Park -after Sugar Creek which winds just to the north of that road. The soy bean field where so many lives came to an end now supports corn, as well as a memorial to the lives lost on Allegheny Flight #485. It does not mention the trauma still suffered by the families left behind and the witnesses forced to clean up the disaster. Air travel is far safer today than it was in 1969, but the path to that safer world is never as direct or simple as the memorial suggests.
