Current exhibition in Berlin. I haven’t been, but sounds interesting. Has anybody heard of the events before?

Yep. A few others happened around Germany during the middle ages. For example in Nuremberg: https://en.wikipedia.org/wiki/1561_celestial_phenomenon_over_Nuremberg https://en.wikipedia.org/wiki/1561_celestial_phenomenon_over... During the second world war in Germany these cases got labelled as "Foo fighters" by the British/US military (not the music band): https://en.wikipedia.org/wiki/Foo_fighter https://en.wikipedia.org/wiki/Foo_fighter Also curious is this recent case in Portugal witnessed by thousands: https://en.wikipedia.org/wiki/Miracle_of_the_Sun#The_event https://en.wikipedia.org/wiki/Miracle_of_the_Sun#The_event I'm interested on the topic because I've personally saw a foo fighter event two decades ago. This was at a portuguese air force location (São Jacinto, summer 2001) during the night. Mind you that we were professionally trained to recognize flying devices. Nobody recognized what the heck those things were. Just two bright balls flying/stopping at incredible speeds with changing angles of direction that defy flying logic. Modern quadcopter drones are coming close to what we saw that night. Still, the foo fighter movements were far more refined. There was no visible influence from the wind on them, perfectly stabilized stop/go flight paths and flying for 4+ hours. Too many people working on the air force will eventually come across such an event at some point in their career. My current guess is that propulsion for those devices is likely electrostatic: https://www.sciencedirect.com/topics/engineering/electrostatic-propulsion https://www.sciencedirect.com/topics/engineering/electrostat... but still left clueless on what kind of power source is used.

  Fascinating, thanks for sharing!
