Adding to the incident news Sun reported " Frantic radio chats were taped between the respected pilots – one bound for Britain – and airport control tower staff in the skies over Athens.But the recordings were hushed up by the Greek authorities who claimed what the pilots saw was just the planet VENUS"

Sun only published censored scanned document. But here we have both version Top Secret as well censored document (in Greek language, obviously) at:  http://www.ufoblogger.blogspot.com/.

So now, you can clearly figure it out which all conversations are missing in the censored document."
