A man and his adult son were aboard a small private plane that was wrecked Tuesday after it collided midair with an F-16 fighter jet over South Carolina, officials said. The body of Michael Johnson, the 68-year-old passenger, was found in a river near the crash site in the rural town of Moncks Corner, Berkeley County Rescue Squad Chief Bill Salisbury said at a news conference Wednesday. Authorities are still searching for the body of his son, Joseph Johnson, the 30-year-old pilot of the Cessna 150. The Johnsons had left the Berkeley County Airport in Moncks Corner shortly before 11 a.m. ET Tuesday, officials said. The men were headed for Myrtle Beach for the day. The pilot of the fighter jet managed to eject from the aircraft and parachute safely in a plantation.
