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.
They also claimed that they hadn't seen Wartena when they began their descent, since they usually avoided human contact. But they also said they had come "to gather information, leave instructions, or give help where needed."
They told Wartena that their ship was powered "by hydrogen extracted from water, that created its own gravitational field." When Wartena left the ship, it rose straight into the air and quickly disappeared.
