I was going to my tution. of 10th class about 5.5 years ago from now. sky was all clear and it was an afternoon of summers. suddenly i noticed that something flashes, sparkes and lights appears in sky with huge amount. and it seems that something object disappeared. but all sky was visible but no object, no airvraft nothing was there instead of huge lights, sparks, and flashes type. and it appeared for5 to 10seconds. i was fully confused what was that agter that i rushed to tution classes. and told everybody about it. but, all of them including tracher make fun of me and nobosy believe in me. but now it has came 5.5 years after that incident but still that thing is stuck in my mind thta what the hell was that. im shure that no. airplane was there because if there was an airplane then it must be sound. aomething but no sound of plane. nothing but onky lights flashes
