What I reported was taken down by a stenographer and made part of the official records, but I did not give them my story in narrative form. The information I was able to give was naturally of interest to various branches of the service, and experts in every line of government work took it in turns to question me. One morning would be devoted, for instance, to answering questions of a military nature--German methods behind the front-line trenches, tactics, morale of troops, and similar matters. Then the aviation experts would take a whack at me and discuss with me all I had observed of German flying-corps methods and equipment. Then, again, the food experts would interrogate me as to what I had learned of food conditions in Germany, Luxembourg, and Belgium, and as I had lived pretty close to the ground for the best part of seventy-two days I was able to give them some fairly accurate reports as to actual agricultural conditions, many of the things I told them probably having more significance to them than they had to me. There were many things I had observed which I have not referred to in these pages because their value to us might be diminished if the Germans knew we were aware of them, but they were all reported to the authorities, and it was very gratifying to me to hear that the experts considered some of them of the greatest value. One of the most amusing incidents of my return occurred when I called at my banker's in London to get my personal effects. The practice in the Royal Flying Corps when a pilot is reported missing is to have two of his comrades assigned to go through his belongings, check them over, destroy anything that it might not be to his interest to preserve, and send the whole business to his banker or his home, as the case may be. Every letter is read through, but its contents is never afterward discussed nor revealed in any way. If the pilot is finally reported dead, his effects are forwarded to his next of kin, but while he is officially only "missing" or is known to be a prisoner of war they are kept either at the squadron headquarters or sent to his banker's. In my case, as soon as it was learned that I had fallen from the sky it was assumed that I had been killed, and my chum, Paid Raney, and another officer were detailed to check over my effects. The list they made and to which they affixed their signatures, as I have previously mentioned, is now in my possession and is one of the most treasured souvenirs of my adventure. My trunk was sent to Cox & Co. in due course, and now that I was in London I thought I would go and claim it. When I arrived in the bank I applied at the proper window for my mail and trunk. "Who are you?" I was asked, rather sharply. "Well, I guess no one has any greater right to Pat O'Brien's effects than I have," I replied, "and I would be obliged to you if you would look them up for me."
