I am civil engineer so i know physics laws exactly i truly know what i saw last night,i was standing in my balcony and drinking tea and looking to the night sky that was time i saw it clearly,a bit shiny blue dot like an star like an airplan going slow slat first but i realized it hadnt navigation lights so it wasnt airplan but suddenly it turned to fast in staright path and change its direction 90 degree to the north_east i was shocked it wasn't in our atmosphere cuz when it was going with that speed no light trail was behide it,i know no one will believe me but i know what i saw and i never forget tgis date...
