Around 6:10 p.m. on November 18, 1973, four young women travelling from Tracy toward Montréal reported a small luminous ball accompanying their car. Their ages are given as fourteen to twenty-four. The light was compared to a watermelon in size and described as white or yellowish, sometimes ahead of the car and sometimes behind it at a distance.
The route narrative includes the ball near a pylon and over the St. Lawrence, with changes in apparent size and brightness as the women drove through wooded stretches. They also encountered a pink cloud or reddish dust lying across the road. After emerging from it, they reportedly had to avoid a short figure in dark clothing and a helmet with hanging flaps, apparently sweeping the painted centre line with a broom. They could not make out its face. A car and several dark-clothed people were also mentioned farther along the roadside.
Marc Leduc and Claude MacDuff are associated with the original inquiries; a 1975 UFO-Québec article and later Canadian histories preserve the sequence. The observations occurred during a wider night of reports in the region, but that does not establish one cause. The sweeper’s relationship to the luminous ball remains conjectural: the account does not show it entering or operating a craft.
The presenter explicitly considers an ordinary human street sweeper at 58:14–58:34. The figure’s connection with the aerial light is unproved, as the dossier already states.
