Reported to be the prototype Junkers-J 13 is Annelise, seen here on September 13, 1919, the day on which it established an unofficial world record by carrying eight people to an altitude of 22,145ft. It is almost certain that in this photograph the wing is of greater span than the original J 13 wing.

The Junkers-J 10 used on the Dessau-Weimar service in 1919. It is almost certain that the Junkers-J 10 was the first all-metal aeroplane to operate an air service. One passenger or a limited amount of cargo could be accommodated beneath the hinged enclosure over the rear cockpit.
