There are buildings like Otto Lilienthal’s Berliner Maschinenbaufabrik that are still associated with the history of aviation to this day. Should Daniel Wiegand achieve his goals, the hangar of his company Lilium could one day be part of it. Wiegand, 36, is the co-founder and head of Lilium. Since it was founded in 2015, the start-up has raised around $ 380 million in venture capital. The company is now merging with the shell company Qell in order to be listed on the US technology exchange Nasdaq. In Oberpfaffenhofen near Munich Wiegand wants to realize a dream with 700 employees: electric taxis that fly.
