Having completed its part in another devastating raid on the Nazi supply system, the U.S. Army 9th Air Force B-26 Marauder bomber is seen over the Channel headed back for its base in England, June 16, 1944. These hard-hitting medium bombers shuttle back and forth across the Channel helping to clear the way for the advance of ground forces. Far below can be seen scores of Allied Naval Craft, dogwatching, supplying and supporting the Allied Expeditionary Forces. (AP Photo)
