Mürren, 12. August 1910:
One hundred years ago Eduard Spelterini was the first man who crossed the Alps in a balloon.
At 1 p.m. Spelterini sang the Torero's aria from Bizet's Carmen, opened a bottle of champagne and then lifted off.
(He always used to make this ceremony on his numerous balloon starts.) In his balloon "Sirius" he climbed up to
4000 m and crossed the Alps in direction of Torino. Six hours later his balloon landed at the versant of Monte Basso in Italy.
