The AT-6 was designed with places for machine guns in the wings and we were sent in groups to Elgin Field in Florida for gunnery practice. This was the field where General Jimmy Doolittle trained his crew for the bombing of Japan. They practiced for months at bomber takeoff from a field the same length as the deck of a carrier which had never been done. That was the only way they would be able to reach Japan. We were assigned there for about two weeks practicing by shooting at ground targets on a large restricted area. We didn't do any shooting at targets in the air, Just dove down shooting at the ground. I recall it being very hot and muggy there off the Gulf of Mexico. After returning to Napier Field we were nearing graduation time. We had now developed a lot of confidence in our flying and fooled around when flying without our instructors. We would fly very close together and tap our wingtips and the wing of the plane flying next to us. Flying close to the ground was fun also and gave you a better idea of how fast you were actually going than you had at high altitudes. In Primary I flew 60 hours, in Basic 72 hours, and in Advanced 97 hours for a total of 220 hours. There were about 250 of us in the class and by that time we had become acquainted with most everyone and close friends with many. We went all the way through combat with some of those same follows. After our final flight with the commanding officer we were ready for graduation. We then filled out forms giving our preference for the type of flying we wanted. Just before graduation they put on an airshow for our benefit. Little stunt planes would fly straight up and all types of fighter planes did acrobatics and speed. Naturally we almost all wanted to get into single engine fighters so that is what we had listed on the forms. I don't remember much about graduation except many of the fellows had their parents there. We were now second lieutenants in the Army Air Force which was a wartime addition to the regular U.S. Air Force.
