After shooting down a German aircraft, Maj. Edward “Mick” Mannock, the Royal Air Force’s all time leading ace, is hit by ground fire that causes his fuel tank to explode. His S.E. 5a aircraft dives into the ground and he is killed. He is posthumously awarded the Victoria Cross, Britain’s highest award for valor. Major Mannock is generally given credit for 73 aerial victories, although several sources put his total lower.
United Launch Alliance’s new Vulcan Centaur rocket is slated to fly its second national security mission in February—nearly six months after its first operational launch and almost a year after it was certified to fly military payloads for the Space Force.
