What happened to Payne Stewart?

What happened to Payne Stewart?  The late Payne Stewart, who died in a plane crash near the town of Mina, South Dakota on October 25, 1999, aged 42, was an American golfer who won 11 times on the PGA Tour. Known for his sartorial flamboyance, characterised by his signatue plus-four trousers, polo shirt and traditional flat cap cap, often in garish colours, Stewart won the PGA Championship in 1989 and the U.S. Open twice, in 1991 and 1999.

At the time of his death, Stewart was en route from Orlando, Florida to Dallas, Texas for the Tour Championship, scheduled to start at the Champions Golf Club in Houston later in the week. However, shortly after take-off, air traffic control lost contact with the chartered Learjet in which he was travelling.

Crash investigators from the National Transportation Safety Board (NTSB) subsequently concluded the loss of cabin pressure led to both pilots and all four passengers becoming incapacitated due to lack of oxygen, a.k.a. hypoxia. Indeed, the aircraft was intercepted by several F-16 fighter jets, the pilots of all of which reported that the windows were frozen over, with no sign of life on board. Nevertheless, the Learjet continued to fly, on autopilot, until hours later and thousands of miles off-course, it ran out of fuel and nose-dived into the ground at high speed.
