The family of Captain Jackson was told that on Sunday evening, word had it that Nha Trang was about to be under rocket and mortar attack. Jackson and his commanding officer headed for the jeep. Jackson dropped off his C/O at one aircraft and drove to his own. Apparently, the destination was Ton Son Nhut air base.
June 27, 1965, while on final approach, Jackson's C123 started receiving ground fire and subsequently crashed. Rescue crews arrived at the scene and found that there were no survivors. The FBI was brought in to fingerprint all on board however, and none of the bodies could be identified as Capt. Carl E. Jackson, USAF or Sgt. Billie Roth.
