After his detachment to investigate reconnaissance issues in the United States (see the Hughes scandal section below), Roosevelt received command of the 8th Air Force's reconnaissance wing in England: the 8th Provisional RW, later renamed the 325th Reconnaissance Wing. During this period, Roosevelt worked on the shuttle-bombing project with the USSR, and participated in the May 1944 mission to the USSR which inspected the new American bases at Poltava, Mirgorod, and Piryatin. His units also supported the D-Day invasion of Normandy and the bombing campaign against V-weapon sites.
