Airman 1st Class David Knutson, 627th Force Support Squadron evaluations technician, swims alone to help raise awareness for victims of post-traumatic stress Aug. 25, 2014, during the Swim to Live event in the Bellingham Bay, Wash. Joined by members of the U.S. Army, U.S. Coast Guard and Canadian Armed Forces, McChord Airmen jumped into the Bellingham Bay just and took turns swimming as long as their bodies would allow before tagging out with another swimmer.
