The 100th anniversary of Europe's first ever airmail service has passed almost unnoticed. But we keep guard, rest assured!
Back in 1919, on 5 February, the company Deutsche Luft-Reederei started regular two times a day flights between Berlin and Weimar, carrying mail and newspapers with the use of ex-military biplanes.
By end-year, it transported a total of 2,385 kg of ordinary post and 7,537 kg of newspapers, which gave an average of about two and 25 kg of letters and red-top, respectively, per flight (though there was no press on the backhaul).
