The Tragic Flight of John F. Kennedy Jr.in Piper PA-32R-301, Saratoga II (N9253N) Near Martha's Vineyard, MA

On July 16 1999, a Piper PA-32R-301, Saratoga II (N9253N), crashed into the Atlantic Ocean approximately 7 1/2 miles southwest of Gay Head, Martha's Vineyard, Massachusetts. On-board were John F. Kennedy Jr., his wife Carolyn Bessette, and sister-in-law Lauren Bessette, all of whom tragically died on July 16, 1999. The Piper Saratoga aircraft was being piloted by John F. Kennedy Jr., originating from New Jersey's Essex County Airport, was en route to Martha's Vineyard Airport, following a coastal path over Connecticut and Rhode Island Sound. The crash resulted in three fatalities and led to the total destruction of the aircraft. Kennedy, who was not certified for flying solely with instruments, faced challenging visual flight conditions during the journey, with obscured landmarks due to the weather and light.

The NTSB investigation concluded that Kennedy experienced spatial disorientation while descending at night over water, causing him to lose control of the plane. Despite being a certified private pilot, Kennedy lacked an instrument rating and was therefore restricted to flying under visual flight rules (VFR). On the night of the crash, visibility was reduced, and there was no clear visual horizon, conditions which are particularly challenging without instrument flying skills. The report highlighted Kennedy's limited flying experience, particularly at night and without a certified flight instructor, and emphasized that illusions and spatial disorientation are common causes of accidents in adverse weather conditions and at night. The investigation found no evidence of mechanical malfunction, stating the probable cause of the accident as the pilot's failure to maintain control due to spatial disorientation, exacerbated by haze and darkness.

Amelia™

Amelia™ provides Flight Envelope for the aircraft and Health Envelope for the pilot that is an add-on, integrating in a non-intrusive fashion to the avionics. Kennedy’s spatial disorientation due to haze and dark night resulted in his failure to maintain control of the airplane during a descent over water at night. He may have not been able to accurately determine the attitude or motion of the aircraft in relation to the earth's surface. Amelia™ Flight Envelope would have helped him to get an intuitive sense of his position even though he was not IFR (Instrument Flight Rule) certified. Amelia™ Flight Envelope is not meant to be a substitute to IFR instrumentation in the aircraft but an add-on that can help the pilot to monitor and gauge the aircraft’s performance and operation. Amelia™ provides a novel 3D holographic interface to the Flight Envelope, which would have assisted Kennedy pilot when he entered the haze and night setting over the water.

In addition, Amelia™ Health Envelope would have kept track of Kennedy’s health and Amelia™ would have helped as a companion co-pilot to keep the pilot calm during the while crossing the 30-mile stretch of water to its destination, about 34 miles west of Martha's Vineyard Airport. This phase of flight was the also the phase of the flight where Kennedy’s aircraft began a sharp descent ranging from 400 to 900 feet per minute (fpm), that resulted in the crash after a fatal right turn where the aircrafts’s rate of descent and airspeed increased dramatically.
