Dickson graduated from Tuskegee in Alabama March 25, 1943. He was sent to Italy and assigned to the 100th Fighter Squadron, 332d Fighter Group. On December 23, 1944, Dickson was on his 68th mission piloting his aircraft as part of a mission to Praha, Czechoslovakia. On the return flight he ejected from his P-51 aircraft over Austria. The aircraft was flipped upside down and Dickson was declared missing in action. Early in the mission Dickson reported engine trouble and notified his base in Ramitelli, Italy that he needed to return. Dickson broke from the mission and two wingmen escorted Dickson's sputtering plane. The trio gradually lost altitude, and Dickson looked for a spot to land or bail out. One of Dickson's wingmen thought they were near the town of Tarvisio, in a mountainous area of northeastern Italy. Dickson's two wingmen followed but they were forced to take evasive action when Dickson's plane sputtered and dove: Dickson's engine trouble was catastrophic and he was forced to eject over Hohenthurn, Austria. One of Dickson's wingmen insisted that he saw Dickson eject but the December snowfall complicated the search for Dickson's white parachute. Dickson was declared missing in action. After the war it was revealed that German records had reported that a P-51 plane crashed at that site the day that Dickson disappeared. During World War II the United States Army was segregated and black pilots had different rules. The black pilots of the Tuskegee Airmen could not qualify for R&R until they completed 70 missions. White pilots could take R&R after 50 missions. Dickson was on his 68th mission when he went missing over Austria.
Recovery and burial
On July 27, 2018, Dickson's remains were identified by the Defense POW/MIA Accounting Agency. A local researcher named Roland Domanig discovered the crash site and the human remains. The researcher said he visited the site in the 1950s as a child, but had not discovered the remains until 2002. An archeological crew was sent to the site in 2017 and they recovered bone fragments which matched Lawrence Dickson's daughter's DNA. Also recovered at the crash site was a 14-karat ring with an inscription that was inscribed: “P.D.,” with a heart with an arrow through it. The ring also was inscribed “L.E.D. 5-31-43.” P.D. were the initials of his mother Phyllis Dickson. L.E.D. Lawrence E Dickson and May 31, 1943, was his 23rd birthday. The Army also recovered a remnant of a harmonica and a small cross. On March 22, 2019 Lawrence E. Dickson was laid to rest in a ceremony at Arlington National Cemetery. Four Air Force jets flew overhead while his daughter and grandchildren attended. His daughter Marla accepted the folded American flag from a kneeling Army General.
Lawrence Dickson was born to Agnes C. Dickson and he had two brothers. He was married to Phyllis. Dickson and his wife had a daughter. On July 14, 1942, at Harlem’s Sydenham Hospital, Marla Dickson was born. Dickson's mother did not live to attend the burial of her son: Phyllis died December 28, 2017, in Nevada at the age of 96.
