Colmar. -- Last night, around 11:30 p.m., two people, the well known night watchman of the "SITRAP" Mr. K. F., and his accompanist, Mr. X. S., of Wettolsheim, saw in the sky on the north side, an amazing glow moving at high speed from east to west, from Fribourg to beyond the Hochkönigsburg in the Vosges. It looked like a round and white disc large of about fifteen centimeters, leaving behind a blue red trail. The appearance resembled almost perfectly to the description that was made in a weekly magazine.
The witnesses formally admit that it was a flying saucer, not a large shooting star.
