Five seperate crafts ziping north in Hinton AlbertaI'm an Entertainer-Recording Artist,I was preforming in Hinton, Alberta Canada,1985.After the show I went Running,and then a freehand workout at the town park.I leaned back on a picnic table to do some leg ups, and over my head about 50 feet,a round glowing craft was zigging north at what i would guess to be around 500-1500 MPH.I little stund,I contiued to watch the sky,and wihtin a few second 4 more similar krafts ziped by weaveing very quickly,in a tight group.I was amazed that they were not smashing into each other.It was cloudly the cieling was about 4 or 5000 feet.I'll never forget the way they moved so quickly,zigzaging with no sound.((NUFORC Note: Date may be approximate, although the witness does not state that as being the case.
