When we first saw the UFO me and Alain B. were at the location no.1 on the map (Chemin Lac Canard). The object produced no sound and was the size of a school bus , (orientation north -east 20 degree) .When we noticed its presence we started running for 872' toward my house (315 Chemin grand-rang). The object took some altitude went toward location no.2( orientation north- west 330 degree) faster than us. We went into the house alert my mother we looked at the object from the inside and saw it slowly going toward the no.3 location ( orientation north-west 300 degree).
