In 1993 at a company party, Hoy was showing a bunch of interns at the law firm where he worked that it was not possible to break the glass in the Toronto-Dominion Centre. He ran across the room on the 24th floor and flung himself into the glass and bounced off. He had done this stunt many times in the past and on this night he tried a second time. The glass shattered and Hoy fell 24 stories to his death. (There was a professional baseball player whose name was Dummy Hoy.)

Tom and Eileen Lonergan

In 1998 the couple went on a scuba diving trip off Australia’s Great Barrier Reef. They lost track of the time and remained underwater at the boat’s scheduled departure time. One of the boat’s crew members miscounted how many people were on the boat and the couple was stranded at sea. No one even realized they were missing for two days until someone found one of their bags under a seat on the boat. Despite a massive search their bodies were never found though some of their stuff washed onshore including a desperate plea for help on a waterproof tablet. Speculation surfaced they had faked their own deaths but their bank accounts were never touched and life insurance policies remain unclaimed. Their story was the subject of the 2004 film Open Water. Chilling to watch as the sharks close in.

In 2000, 19 year old Jonathon Burton went crazy and stormed the cockpit door of Southwest Airlines Flight 1763 from Las Vegas to Salt Lake City, Utah. Eight passengers grabbed him and threw him to the floor. An off duty police officer was escorting him to the back of the plane with another man’s help when Burton went crazy again and punched the officer in the mouth. Burton was again thrown to the floor of the airplane and allegedly a large burly man repeatedly slammed himself onto Burton’s chest. Burton was still alive when the plane landed but died soon after of acute asphyxia. No one was ever charged.

In 2003 the couple were killed and partially consumed by a grizzly bear in Alaska while Treadwell was filming the bears. Treadwell had been going to Alaska for 13 years and living among and filming the bears. The incident was not directly filmed as the camera was facing away but the audio captured the gruesome details. In 2005 film maker Werner Herzog did a documentary film, Grizzly Man, which discusses Treadwell and his death, including the audio clip. Another chilling film.

In 1979 at a Ford Motor Company plant in Flint Michigan, Williams became what is believed to be the first human killed by a robot when he was ordered to retrieve a part from a storage bin because the robot assigned to that job was being too slow. As Williams grabbed the part the robot’s arm swung around and hit him in the head killing him instantly. Williams family was awarded $10 million dollars in damages.

Janet Parker 

In 1978 Janet Parker was working as a medical photographer at the University of Birmingham Medical School when a researcher at the lab she was working in accidentally released the smallpox virus into the building and it killed Parker. Smallpox had been wiped out in the wild and only existed in labs at that time. Parker’s death led to the suicide of Professor Henry Bedson who was the head of the microbiology department. Parker is believed to be the last human smallpox fatality in history, at least until another accident or worse happens.

Payne Stewart 

In 1999 the Learjet carrying golf professional Payne Stewart, his two agents, a Jack Nicklaus golf course designer and two pilots lost cabin pressure and all aboard died of hypoxia or lack of oxygen. The incident occurred in mid-flight and the Air Force had to send fighter aircraft to monitor the flight of the pilot-less jet. The Lear’s windows were observed to be clouded over with frost due to the lack of cabin pressure. Reportedly the Air Force was prepared to shoot down the Learjet if it ran out of fuel near any type of populated area. After a few hours of pilot-less flight time the plane ended up running out fuel and crashing in the middle of nowhere in North Dakota. Stewart had won the US Golf Open at Pinehurst just 4 months prior to his death.
