14 October 1943: A large force of 8th Air Force heavy bombers and escorting fighters attack the ball bearing factories at Schweinfurt, Germany, for the second time. Five bombardment groups sent 291 B-17 Flying Fortress four-engine heavy bombers on the raid.

60 B-17s were shot down by German fighters or anti-aircraft artillery (“flak”). Another 17 were so heavily damaged that they crashed on landing back at their bases, or were so severely damaged that they were beyond repair. 121 B-17s received lesser damage. 594 crewmen were listed as Missing In Action (presumably Killed In Action). 65 men were captured and held as Prisoners of War. Of the bombers that returned to England 5 crewmen were killed and 43 were wounded. B-17 gunners shot down 35 to 38 Messerschmitt Bf 109s and Focke-Wulk Fw 190s. Another 20 fighters were damaged.

17 August 1943: Mission No. 84. One year after the Eighth Air Force first attacked occupied Europe with its B-17 Flying Fortress four-engine heavy bombers, a mass attack of 376 B-17s attacked the Messerschmitt Bf-109 factory at Regensburg, Germany, and the ball bearing factories at Schweinfurt.
Over Germany for over two hours without fighter escort, 60 bombers were shot down and as many as 95, though they made it to bases in Allied territory, were so badly damaged that they never flew again. 55 air crews (552 men) were listed as missing in action.
Of the 146 B-17s of the 4th Bombardment Wing which attacked Regensburg, 126 dropped their bombs, totaling 298.75 tons (271.02 Metric tons), destroying the factory and seriously slowing the production of the Messerschmitt Bf 109 fighter. After the attack, the 4th Bomb Wing headed for bases in North Africa. 122 B-17s landed there, half of them damaged.
The 1st Bombardment Wing (Heavy) sent 230 B-17s to Schweinfurt. Weather delays caused the planned diversion of two separate attacks to be unsuccessful. Cloud buildup over the Continent forced the bombers to fly at 17,000 feet (5,182 meters), nearly 10,000 feet (3,048 meters) lower than planned, increasing their vulnerability. Just 183 bombers made it to the target and dropped 424.3 tons (383.9 Metric tons) on the five factories in the target area. Then they headed back to their bases in England, under fighter attack most of the way. The 1st Bombardment Wing lost 36 bombers.
Though the raid did cut production of ball bearings as much as 34%, the losses were quickly made up from stockpiles. The two attacking forces succeeded in shooting down 25–27 German fighters.
