May 19, 1929
See Original Daily Bulletin From This Date

The Ullstein 5,000 mark prize for the longest sustained flight of a heavier-than-air machine without a motor was won by Robert Kronfeld, Austrian Jewish student. The Berlin press today devotes much space describing the invention and the achievement of the young student.

The distance set in the test flight was 100 kilometers. In his machine, which has sails to sustain it in the air, Kronfeld flew over Teutoburgwald, covering 145 kilometers, a distance more than twice that covered previously by motorless aircraft.

Kronfeld received a subvention from the Vienna municipality of 6,000 schillings last week for the construction of his machine.
