Tell Us What You Thought Of This Episode

Mark "Trunk" Kirschenbaum is a skydiving photographer, electrical engineer, and founder of Hypoxic — the go-to source for camera equipment in human flight. After designing the Hypeye D Pro, a video controller and indication system that sold over 13,000 units, Trunk left his corporate engineering career behind to pursue Hypoxic full-time. Today, his products are used by professionals worldwide.

In this can't-miss episode, Trunk shares the origin of his nickname, his work as a camera coordinator alongside Joe Jennings on commercial shoots and the film Space Cowboys, the thrill of world-record big-way skydives, and hard-earned lessons about camera safety. He also opens up about managing anxiety, his decision to stop drinking, and the joy of life with his wife Julie — a fellow skydiver he met at Couch Freaks.

Presented by SSK Industries, CYPRES, Free Fall Films, SKYCRU and Burble.
