i was visiting the hotel queen wilhemina i walked out to the observation desk outside the hotel. i was taking pictures as the sun was setting. i did not see it, or hear anything, it was just in my pictures and maybe a video when i got home. i do not know size or how far it was. i did not see anything. i was zooming in and out on pictures i was taking so size is hard to say. it's interesting so i'm sharing. note: i'm adding a video i also took out there, it's short, just landscape video. but at the very end something flies into frame and moves around. i can't tell if its a space craft it looks like a hat upside down.. just found it. i'm including it, but may not be anything.
