extrem seltener Ballonpostbeleg von der 1. Überquerung der Nordsee am 12.10.1907 Chrystal Palace/England- Schweden des Ballon"Mammoth".
Interessant dabei,dass der Text auf der Karte bereits am 09.09.1907 geschrieben wurde, wohl wegen meteorologischer Gründe die Fahrt erst am 12.10.1907 erfolgte


most spectacular take off took place on
the 12th October 1907 when the
"Mammoth" (3'000 m3 ) started from the Crystal Palace, London, with its
pilot AF Gaudran and two English passengers on board. After 19 hours in
the
air the trio landed safely on the shores of Lake Väner, north of the
Swedish port Göteborg. They found themselves 1'175 km away from the
Thames
and had flown over 700 km of water without an interval.
