U.S. Air Force F-15C pilots from the 173rd Fighter Wing train on a simulated parachute drag, releasing their harness while being dragged behind a personal watercraft at Cultus Lake, Oregon, July 25, 2019. The training occurs every three years and is necessary for flying and training the F-15C over water, something these pilots do when using the ranges over the Oregon and California Coast.
