GERMANY: The Messerschmitt Me 262 prototype had its first test flight, although only with a piston engine at first. The Me 262 V1 example, bearing its Stammkennzeichen radio code letters of PC+UA, since its intended BMW 003 turbojets were not ready for fitting, used a conventional Junkers Jumo 210 engine mounted in the V1 prototype's nose, driving a propeller, to test the Me 262 V1 airframe. The V1 through V4 prototype airframes all possessed what would become an uncharacteristic feature for later jet aircraft designs, a fully retracting conventional two wheel gear setup with a retracting tailwheel.

Angler POW Escape: 80 prisoners attempted to escape from the Angler POW camp near Neys Provincial Park in Ontario, Canada. The Angler Camp was designed to hold prisoners who were a threat to Canada. As a result, several German POWs were held there. A tunnel was dug 45 m (150 ft) long that reached outside the wall, with side tunnels entering some of the barracks. The ground under and around the camp was mostly sand, making it easier for the prisoners to dig a tunnel. The initial intent was for 100 prisoners to escape, but the escape was interrupted, when a guard heard noises made by the prisoners and alerted the rest of the camp. Most were quickly apprehended except for two who managed to get all the way to Medicine Hat, Alberta by train until they were recaptured. Though they were given 28 days of solitary confinement at the Camp for their actions, they were asked to sign autographs in Alberta before returning and were greeted upon their return by the Commandant who said, "As a sportsman, I congratulate you…" Horst Liebeck was sent back to Germany after the War with the other POWs, but he later returned to Canada and got a job there.
