Let’s say there was a video camera a mile up river from where these men say they were abducted.
The video recorded would be of very low quality in comparison to today. (240 X 333 lines of resoulution)
The black and white cameras also had a high light requirement. Anything poorly lit was not going to show up.
Given that rivers are not necessarily straight and river fronts are often built up the cameras of the day were typically made for focusing on near objects especially in low light, I would be surprized if they caught any thing happening a mile away at night.
Anything happening a mile away caught by camera in the early 1970’s at night would have to have been of biblical proportions.
Who said it was a mile away? I liked the Pascagoola story when I first heard it, I’m simply telling you that if you search you’ll find an analysis debunking the story based on a cctv camera which showed nothing happening on that dock that night.
