I dont know these are ufo s or just some light plays and tricks. i took those videos during an airplane show which is called technofest in turkey. my intention was to record planes and i didn't realized them with naked eyes. later when i was checking the videos i saw them. i have 6 or 7 videos all recorded by me and with 2 different smartphones. . i'm really bad at recording and quality is not good. i m sorry for that. i m not saying those are ufo s. i just want to learn what they are. it's s my first time witnessing and recording something like that. i would really appreciate if someone tells me what they are. if they re just some kind of reflection or light play i m sorry for taking your precious time.
