U. S. Army Air Force lost 28 in the years of 1944 and 1945. Referring to the particular MACRs No. 14204 and 14214 and to the German air enthusiast Ulf Podbielski only one Thunderbolt of the 367th Fighter Group (not two as Jiri Rajlich, Czech aviation historian, states) crashed near the town of Tachov on April 16, 1945.
This was 2/Lt James B. Cutler of 392nd Squadron, while 1/Lt. Frederick W. Cordner of the 393rd Squadron was shot down over the airfield in Riesa, Saxony.
This figure doesn't include machines shot down by AA fire when chasing enemy planes over airdromes. The majority – twenty-one fighters failed to return the home base on April 16 and 17, 1945 when the Eighth and Ninth Air Force conducted massive attacks on Luftwaffe installations in Bohemia and Germany. Recently I added 1/Lt. William R. Preddy a Capt. Raymond F. Reuter of the 339th Fighter Group I didn't mention in the prvious version of this list.
Twelve pilots were killed and fourteen others were captured. One pilot evaded and was hidden by local people. The fate of 2/Lt Frederick W. Turner after he belly-landed on April 29, 1945 is unknown.
