Without any credible citation, it is very difficult to believe. That too, if you are reading about something that is controversial, difficult to believe and belongs to ancient past, then in that case you deal with toughest problem. For example, there is already lot of fuss about UFOs, atlantis and so on. In this crowded space of claims and counter-claims, there is absolutely no need to put something on official pages. Yes, I am talking about the zombie of ancient aeronautics of India. Government of India has a appreciable site ‘Vigyan Prasar‘ for spreading a word about science and technology. The problem is – On the Vigyan Prasar site the information is being displayed about these ancient planes and with no citations at all. Of course there are other such similar claims without any citations, sitting alongside Vigyan Prasar.
