Strange Whistling Noise

Date: June - 1951

Location: Denmark

I heard a strange whistling noise and saw an object land in a meadow.

I approached to within 150', only to find myself completely unable to move.

I noticed that the birds had stopped singing and the cows also appeared to be paralysed.

From the object I saw 4 handsome men come out. They had brown skin and work black shiny suits with translucent helmets.
