6 December 1969 - AIRMAN FIRST CLASS DAVID M. DAVISON.  Boxer-22, an F-4C, goes down in Laos directly over the Ho  Chi Minh Trail, an awesomely fortified transportation network.  During the next three days, ARRS coordinates one of the largest search and rescue missions ever to be conducted in Southeast Asia.  Airman Davison loses his life during the prosecution of this mission.  The search and rescue task force flies 336 sorties and fifty-one hours in support.  Although the F-4 pilot is never recovered, the navigator, First Lieutenant Woodrow J. Bergeron, Jr., is rescued.  Pararescuemen Gene Nardi and Curt "Snake" Phythian are crewmembers on the Jolly that makes the most attempts to effect a recovery.  Nearly forty pararescuemen participate in direct action against the enemy.  Some are wounded in the fray.  When it is over, five of the ten helicopters involved never fly again because of the battle damage.  Five Sandy A-1's suffer heavy damage.
