NCIS Season 7 Episode 11

Navy test pilot lieutenant commander Brad 'Hondo' Sayer is found half-burn by park rangers in the Virgianian Appalachians. He was flying a jet-pack in his spare time, but it exploded. The manufacturer, Victor Tillman, paid him well as the Navy refused the project, but ignored his ex and competitor Vanessa paid him to fly a prototype she got in the divorce as well. Given his expertise, McGee is made key investigator. Lawyer Margaret Allison Hart is his greatest obstacle. Autopsy by Palmer shows Brad was poisoned before.
