On 16 July 1999, the son of former President John F. Kennedy took off in his privately-owned Piper Saratoga from New Jersey bound for Martha's Vineyard. Although he held a private pilot's license without an instrument rating, he departed in marginal weather at night. Accompanied by his wife, Carolyn Bessette and her sister, they would never be seen again. Due to the mystique surrounding the Kennedy family and the untimely death of another young Kennedy, this mishap continues to consume conspiracy theorists even today.
A simple search for the terms 'JFK Jr plane crash' or other similar word combination initially reveals several credible sources in any search engine’s top sites, but then quickly digresses to blogs from conspiracy theorists. Youtube is also teeming with videos of theories alleging the most absurd explanations for John Kennedy's fatal crash. Although worth reading for a laugh, the reader is soon faced with propositions so ridiculous that I could not with good conscious advertise these sites via links. These 'alternate' explanations usually start from a position that the National Transportation Safety Board (NTSB) cannot be trusted because they are a government agency. This belief is typically deeply founded in a greater suspicion that all governments are direct subsidiaries of secret societies or Lucifer himself with the expressed goal of forming a one-world government that will enslave the human race and usher in the preconditions for apocalypse. From these hypotheses, it naturally follows the JFK Jr was assassinated in order for the mafia to ensure that Yale’s Skull & Crossbones would continue to hand pick wall street bankers and Saudi princes in order to dominate the masses."This post will tack in a slightly different direction, starting from a hypothesis that the NTSB is what it identifies itself as - "an independent Federal agency charged by Congress with investigating every civil aviation accident the United States and significant accidents in other modes of transportation – railroad, highway, marine and pipeline. The NTSB determines the probable cause of the accidents and issues safety recommendations aimed at preventing future accidents."1 The unparalleled safety record that the aviation industry has developed over the past few decades lends weight to the effectiveness of the NTSB's processes.Using rational thought and empirical evidence, a brief summary of the mishap events followed by a list of contributing and causal factors will be explored.
On the evening of 16 July 1999, John F. Kennedy, Jr departed from Essex County Airport (CDW) in his privately owned Piper Saratoga with his wife Carolyn Bessette and her sister Lauren. The flight plan was destined for Barnstable Municipal-Boardman/Polando Field (HYA), with a scheduled stop at Martha's Vineyard Airport (MVY) to drop off Lauren. Because Kennedy filed no official flight plan, the itinerary above was gathered from testimony of friends and family.Taken directly from the NTSB final report: “The noninstrument-rated pilot obtained weather forecasts for a cross-country flight, which indicated visual flight rules (VFR) conditions with clear skies and visibilities that varied between 4 to 10 miles along his intended route. The pilot then departed on a dark night. According to a performance study of radar data, the airplane proceeded over land at 5,500 feet. About 34 miles west of Martha's Vineyard Airport, while crossing a 30-mile stretch of water to its destination, the airplane began a descent that varied between 400 to 800 feet per minute (fpm). About 7 miles from the approaching shore, the airplane began a right turn. The airplane stopped its descent at 2,200 feet, then climbed back to 2,600 feet and entered a left turn. While in the left turn, the airplane began another descent that reached about 900 fpm. While still in the descent, the airplane entered a right turn. During this turn, the airplane's rate of descent and airspeed increased. The airplane's rate of descent eventually exceeded 4,700 fpm, and the airplane struck the water in a nose-down attitude.” These events unfolded during the last 7 minutes of the mishap flight.1
The mishap airplane, N9253N, was a Piper PA-32R-301, Saratoga II, single-engine, low-wing airplane with retractable landing gear. The airplane was originally certificated by Piper Aircraft Corporation on June 9, 1995. After several previous owners, it was eventually purchased by Kennedy on April 28, 1999. According to the maintenance facility employee, "the aircraft was found to be in very good condition, with only a few minor discrepancies." According to the records and the maintenance facility employee, an annual inspection was completed on June 18, 1999, at a total airframe time of 622.8 hours.Upon recovery of the wreckage, the tachometer indicated 663.5 hours. There were no significant mechanical failures demonstrated upon analysis of the wreckage and flight data recorder. The aircraft was equipped with a digital voice recorder; when found in the wreckage, it was crushed, its backup battery was missing, and it had retained no data. After the incident, the propeller and engine were examined. Neither revealed evidence of any preexisting failures or conditions that would have prevented engine operation. The aircraft was equipped with an Automatic Flight Control System (autopilot system). Post-mishap investigation did not reveal any evidence of a pre-impact malfunction or jam. The aircraft’s GPS unit was crushed, but the switch was found in the ON position. The flight command indicator displayed a position that indicated a right turn with a bank angle of about 125 degrees and a nose-down pitch attitude of about 30 degrees. The gyro display was captured in a position indicating a steep right turn. The heading indicator was pointing to 339 degrees. On the airspeed indicator, the needle mark was consistent with the maximum mechanical needle travel position for the airspeed indicator design.INTERPRETATION: The aircraft was documented to be airworthy without any significant discrepancy prior to flight. Examinations on the wreckage indicated there was no failure of the engine, propellers, avionics or other hardware. The flight instruments were essentially frozen in time demonstrating various flight parameters of the aircraft when it impacted the water. All evidence corroborated a scenario in which the aircraft was rapidly descending and engaged in an aggressive right turn upon impact. There was no voice data to evaluate conversations among those in the cockpit or across radio communications during the flight.
These observations indicated that visibilities varied from 10 miles along the route to 4 miles in haze. The lowest cloud ceiling was reported at 20,000 feet. These observations were made about 1800. His takeoff time was 2038 local. It appears that Kennedy made two weather requests prior to flight for a route briefing from TEB to HYA with MVY as an alternate. Preflight weather called for VFR (visual flight rules) conditions.Three pilots who had flown over the Long Island Sound on the night of the accident were interviewed after the accident. Before departing the city, one of these pilots had obtained current weather observations and forecasts for similar areas traveled by Kennedy’s aircraft. He stated that the visibility was well above VFR minimums. Relating a preflight call to the flight service station (FSS) before departing he stated: ??"I asked if there were any adverse conditions for the route TEB to ACK. I was told emphatically: 'No adverse conditions. Have a great weekend.' I queried the briefer about any expected fog and was told none was expected and the conditions would remain VFR with good visibility. Again, I was reassured that tonight was not a problem." ??This same pilot also provided testimony about weather conditions over MVY that night. When his global positioning system (GPS) receiver indicated that he was over Martha's Vineyard, he looked down and "...there was nothing to see. There was no horizon and no light....I turned left toward Martha's Vineyard to see if it was visible but could see no lights of any kind nor any evidence of the island...I thought the island might [have] suffered a power failure."Another pilot had flown nearby the same evening at about 1930. This pilot stated that during his preflight weather briefing from an FSS, the specialist indicated VMC (visual meteorological conditions) for his flight. The pilot filed an IFR (instrument flight rules) flight plan and conducted the flight at 6,000 feet. He stated that he encountered visibilities of 2 to 3 miles throughout the flight because of haze. He also stated that the lowest visibility was over water.A third pilot departed TEB (same airport Kennedy departed) about 2030 destined for Groton, Connecticut, after a stopover at MVY. He stated that the entire flight was conducted under VFR, with a visibility of 3 to 5 miles in haze. He stated that, over land, he could see lights on the ground when he looked directly down or slightly forward; however, he stated that, over water, there was no horizon to reference.
JFK Jr had started his flight instruction almost 17 years before the fatal mishap. He logged 47 hours from 1982-1988, but then did no formal flight instruction until late 1997. He earned his private pilot’s license by April 1998. By 16 July 1999, the night of the mishap, John Kennedy was enrolled in an instrument rating course and had completed 12 of 25 lessons, but did not yet possess an instrument rating. Although Kennedy’s most recent logbook was not located the logbook dated thru 11 November 1998 demonstrated 310 hours of total flight time, 55 of which were at night. In the 15 months prior to the crash, JFK Jr had flown 35 flight legs either to or from the Essex County/Teterboro, New Jersey area and the Martha's Vineyard/Hyannis, Massachusetts, area (MVY). About half of these flights were without a certified flight instructor (CFI).One of JFK Jr’s CFI stated to the NTSB that the pilot had the ability to fly the airplane without a visible horizon but may have had difficulty performing additional tasks under such conditions. Another instructor stated that the pilot had the capability to conduct a night flight to MVY as long as a visible horizon existed.
According to New York ATC, an aircraft matching the description and flight path of Kennedy’s plane passed thru its Class B and Class D airspace (both require communication with ATC) alerting the Traffic Alert and Collision Avoidance System (TCAS). This incident provoked ATC to warn a commercial airliner being flown by American Airlines. The entire transcript of the American 1484 pilot and ATC can be found in the NTSB report.
According to medical records, Kennedy fractured his left ankle in a "hang gliding" accident, underwent surgical fixation in June 1999. By the date of the mishap, 6 weeks after his ankle injury, Kennedy had been placed in a Cam-Walker and was using a cane. His medical records noted that he was "full-weight bearing with mild antalgic gait." JFK Jr’s orthopedic surgeon stated that he felt that, at the time of the accident, the pilot would have been able to apply the type of pressure with the left foot that would normally be required by emergency brake application with the right foot in an automobile.Toxicological testing was performed on the human remains, which were negative for any presence of drugs or alcohol.
Much of the national media focused on the many stressors possibly affecting the pilot in command of this mishap. This was likely due to the profitability of the drama of one of the country’s biggest socialite, but psychological stress should not be fully ignored.
Spatial disorientation (commonly referred to as Spatial-D) is the inability to determine or incorrect perception of one’s location and motion relative to their environment. The general term, spatial disorientation can be further divided into a variety of unique categories that can affect aviators.
DATED, SLIGHTLY BORING, BUT INSTRUCTIVE FAA VIDEO DESCRIBING SPATIAL DISORIENTATION:
The NTSB’s final conclusion for the direct cause of this aircraft mishap was "The pilot's failure to maintain control of the airplane during a descent over water at night, which was a result of spatial disorientation. Factors in the accident were haze and the dark night."1Mishaps are never simple, nor are they often due to one specific decision, input, or mechanical failure. An aircraft mishap is usually a result of compounding factors that go unnoticed, eventually lining up in such a way to result in actual catastrophe. For every actual mishap, there are a much greater number of potential mishaps that are first noticed and avoided. The fact that the party was running late may have pressured Kennedy to fly over a patch of featureless ocean as it was the fastest way to cross, but this increased his risk for developing SD.Although many of the other factors listed above may have contributed to this mishap, ultimately pilot error directly led to this fatal crash. The relative limited experience and training by Kennedy increased his chances of experiencing SD and decreased his likelihood of accurately identifying and correcting it. It is quite possible that Kennedy was experiencing the most dangerous type of SD, type 1 or unrecognized SD and did not know he was disoriented until he hit the water. His physical and mental health, along with several other factors noted above may have led to a state of decreased attention and increased distraction, which also are risk factors for vestibular illusions.There is no hidden agenda or conspiracy in this story, just another sad and tragic chapter in the Kennedy Story.
