Slick Operators aired on a show called Scottish Eye on Channel 4 in the UK on January 20, 1990. As far as I can tell there is not another copy on the internet anywhere, not really any info about it either. This was a VHS copy that was given to a friend at a conference in Alaska in 1990, so the quality is what it is.
It investigates BP's role in the Exxon Valdez oil spill in Alaska and shows the companies history of cutting corners on safety to make more money. Things that were said to be impossible in the cover up of the Exxon Valdez spill were routine at an oil terminal in Scotland.
