"The pattern of air transport service over the North Atlantic changed rapidly in response to the Allied successes in land warfare on the Continent. On 31 August 1944, only four days after the last of the German troops left Paris, the Air Transport Command landed its first aircraft at Orly Field, nine miles away. Orly began almost at once to sustain a heavy traffic between the United Kingdom and France. Hardly a month later, on 4 October, the first scheduled ATC plane on the New York-Paris run landed at Orly. By the middle of the month the ATC's C-54's were averaging three round trips daily between the homeland and France, with Stephenville and Lagens as stopping points. "
