Silver, shiny disk zooms over Thunderchild Reservation in July 1984

A couple friends and I saw a very fast and large moving silver, shiny disk zoom by overhead when we were biking on Eagle Road on the Thunderchild Reservation in Saskatchewan during the summer of 1984.  I remember all the dogs on the reserve barking for hours afterwards.  A lot of windows on most of the cars and trailers had broken right after the sighting.  Later, the adults in the community argued that the only explanation would be that a powerful fighter jet had flown by with low altitude but that doesn't make any sense.  We know what we saw. Fighter jets aren't silver and shiny and are not shaped like disks.  Also, why would there be a single fighter jet flying so low to the ground over a quiet, rural Indian reserve in Canada?  It makes no sense.
