At about 6:30 p.m. Ingolf Diederichs jumped from a moving train at a point very close to the Bornholmer Strasse border crossing. When he fell, he got caught on the train and was dragged with it. His head was seriously injured and caused his immediate death.
At around 10:30 p.m. they reached the small garden colony named "Harmonie" in the East Berlin district of Treptow. They waited for more than an hour in a tool shed and observed the border territory, waiting for an advantageous moment to flee.
It was just past 2 a.m. when a police car slowed down in front of the grounds of the control station. Fearing that the balloon did not yet have enough gas to carry two people, they decided that Winfried Freudenberg should take off by himself. He cut the tether cables and rose up into the night sky.
