I think someone tried to pull a bit of a prank on this Boston Reporter.
Back to the Future fans will totally get it and I'm guessing this Reporter is too young and never saw the movie.
If your yourself have never watched Back to the Future, then you also might not be in on the joke.
There is no such thing as a "Flux Capacitor" it's made up from the movie. Sadly, the Reporter didn't know it and I'm sure many Back to the Future fans watching the newscast had a good laugh.
This truly was fake news.
