Whilst filming a shot of the fountain in georgioupoli square crete in slow motion galaxy s8+ and reviewing later i had captured a very fast flying object this appears from right to left of shot from the first tv antenna notice this is behind the antenna's off in the distance so cannot be a bug or bird and if you look at how fast this thing is going compared to the activity captured around in the square ( people walking and fountain). this made no noise and know one had noticed it overhead nor me until video was played back later on that evening .
