The Fokker D.VII is the only aircraft mentioned by name in the Armistice demands of November, 1918. Germany was ordered to surrender “1,700 airplanes (fighters, bombers – firstly, all of the D 7’S and all the night bombing machines)” (number of aircraft to surrender are not always the same).
In the end, not all D.VII’s were handed over. Some were flown back to Germany by their pilots and hidden in sheds. From the ones that were flown to the collection points of the Inter-Allied Control Commission, some were wrecked during landings or taxiing. After the war, some were sold abroad. Anthony Fokker flew from Germany and smuggled six trains with sixty wagons each full of aeroplanes and tools to Holland. Among these were 120 D.VII’s.
Church became the first stewardess to fly (though not the first flight attendant, as German Heinrich Kubis had preceded her in 1912). On May 15, 1930, she embarked on a Boeing 80A for a 20-hour flight from Oakland/San Francisco to Chicago with 13 stops and 14 passengers.
That works out to a potty break about every 90 minutes en-route. In those days, synchronization was everything.
