Thursday afternoon around 4 p.m., two girls of Willer who were working in the fields, Misses B. M., aged 16 and her sister C., aged 20, saw in the sky, passing at high speed, two dark superimposed discs, of oval shape...
They emitted absolutely no light and made no sound. The two dark "objects" quickly disappeared in the direction of Windenhof. The same day, at the same hour, other witnesses, some farmers, also of Grentzingen, also say they saw the two mysterious craft.
