LUDZIE LISTY PISZĄ… – POCZTOWA LINIA LOTNICZA WIEDEŃ-KRAKÓW-KIJÓW-WIEDEŃ W ŚWIETLE ARCHIWALIÓW ÖSTERREICHISCHES STAATSARCHIV-KRIEGSARCHIV WIEN

1 April 1918 was the day the first in history regular postal airline Vienna-Cracow-Lviv-Kiev- -Vienna was launched. The total flight time was 13 hours and the record flight took 11 hours. The route was divided into ca. 350-km-long stages and covering it with cargo was often very difficult, even dangerous. Still, it was that line which was the first regular postal airline in the world. The author has presented two unknown accounts found in the Österreichische Staatsarchiv – Kriegsarchiv Wien, by Captain Doctor August von Raft-Marwil and Major Tanner, describing that extraordinary courier airline which operated for seven months.
