Mark Byrnes has spent most of his life in, on or around helicopters, both maintaining and flying them. At a very young age his father was killed in a helicopter accident, but this didn't stop him from pursuing his dream of one day becoming a pilot. Years later his older brother was also killed in a helicopter accident yet Mark continued his career motivated by both accidents to make the helicopter industry safer.

Sadly the aviation industry has now taken Marks livelihood but in a completely different way.
