A bizarre test drive on an airport runway ends tragically

It's one of the most bizarre accidents Sheriff John Spezze has seen.

Two friends, 71-year-old Lynd Fitzgerald and 76-year-old Roger Lichtenberger, were speed-testing a 2016 Dodge Challenger Hellcat on the runway of Central Colorado Regional Airport in Buena Vista Sunday when something went horribly wrong.

Instead of stopping when they reached the end of the runway, the car kept going at what the Chaffee County sheriff estimates was more than 100 miles per hour.

"They were just test-driving this car. They went a little too fast. I don't want to surmise. They probably got to the end of the runway and, at that speed, didn't realize they were there so fast. And they lost control. It was just too high a speed and they got to the end of the runway," Spezze told the Denver Post.

The Hellcat flew across a ravine, hit the ground, then flipped end-over-end through another ravine. Both men died at the scene.

Authorities said the men had permission to use the runway.

The accident investigation revealed that the car traveled over 600 feet beyond the runway. And troopers did find skid marks, indicating that the men tried to stop.
