There was, is and will be NO ‘UFO’s whatsoever, for they are NOT REAL! and so, are not going to visit us anyway!! It was only a mirage revealed by The United States during the Era of Cold WAR with the erstwhile USSR. During that period, USA was developing their "Stealth Bombers" which were designed in such a way as to evade the radars; as such they were under routine trial runs and were sighted by several people including many pilots (information as revealed by America itself on a past occassion, as I read the news items myself related to the subject..no doubt..)
So, there is NO ‘UFO’ (Un Identified Flying objects) ! So, That was the real story!!
