Overlock, John Francis
Air Force Lieutenant colonel
John Francis Overlock, age 32, from Springfield, Massachusetts, Hampden county.
Service era: Vietnam
Date of death: August 16, 1968
Death details: On August 16, 1968, an F-100F Super Sabre (tail number 56-3865) with two crew members took off from Phu Cat Airbase, South Vietnam, on a forward air controller mission over North Vietnam. The aircraft made radio contact when it was in the vicinity of (GC) 48Q XE 590 445, but was not heard from again. It failed to rendezvous with a tanker aircraft for a scheduled aerial refueling, and then failed to return to base, whereupon a search and rescue operation was launched. Search personnel failed to locate the aircraft or either of its crew members.
Major John Francis Overlock, who entered the U.S. Air Force from Massachusetts, served with the 309th Tactical Fighter Squadron and was the pilot of this Super Sabre at the time of its loss. He remains unaccounted for. Following the incident, the Air Force promoted Maj Overlock to the rank of Lieutenant Colonel (Lt Col). Today, Lieutenant Colonel Overlock is memorialized on the Courts of the Missing at the National Memorial Cemetery of the Pacific.
