Today, 75 years ago: Zeppelin LZ-129 Hindenburg departed Frankfurt at 8.21 a.m. for a round trip over Germany. It was the first zeppelin flight in 1937 and the beginning of the 1937 flight season. During that flight, Colonel General Ernst Udet tried to land with an airplane at the airship. The illustrated card is signed by Udet and also mentiones in the top-left corner that this was the first airship flight in 1937.
Only 6 flights and 56 day left until LZ-129 Hindenburg crashed on May 6, 1937 at Lakehurst, NJ.
