Quote:At an isolated location miner Udo Wartena saw a large disc shaped object about 35 foot high and over 100 feet across hovering above a meadow. The object resembled two soup plates, one inverted over the other and stainless steel in appearance. Wartena then saw a staircase unfold from the bottom of the craft. Out of it came a man who asked him if the ship could take some water. The man then invited Wartena inside the object. Wartena accepted and met another man inside that told him they had come from a distant planet and were 609 years old and the other over 900.

Quote:Donald E. Keyhoe:

“After a one year’s investigation, I believe that the flying saucers seen by veteran airline and Air Force pilots are objects from another planet. The Air Force itself has officially admitted that flying saucers exist. This statement appears in Project Saucer case number 75. Not only that, the Air Force has officially analyzed the motives of possible visitors from space. Here is a direct quotation from the official report:

‘Such a civilization might observe that on earth we now have atomic bombs and are fast developing rockets. In the past history of mankind, they should be alarmed. We should therefore expect at this time, above all, to behold such visitations.’”
