First flight cover
On the return flight (outbound flight: September 5, 1918 - New York - Chicago via Lock Haven, Pennsylvania, Cleveland and Bryan, Ohio), pilot Max Miller left Chicago (having flown there from New York, landing September 6) on September 9, remained overnight at Lock Haven and arrived at Belmont Park the next day. Pilot Edward Gardner and his mechanic, Edward Radel, departed Chicago on September 10 and arrived in New York on the same day but crashed at Hicksville when they could not find the Belmont Park airfield.
Officials used regular machine cancels in all the cities along the route, with Lock Haven again applying a single-line cachet, as was done on the westbound trip. It has been reported that the following amounts of mail were carried: Miller - 148 3/4 pounds (2,974 pieces); Gardner - 3 1/2 pounds (sixty-eight pieces).
Max Miller carried this item from Chicago to New York. The black, circular postmark reads, "CHICAGO / SEPT 9 / 6 AM / ILL." Its return address reads, "CHICAGO - NEW YORK AIRMAIL / FIRST TRIP." It is addressed to Arkin and Co., New York.
