I suspect some east coast people watching the mini-series Loose Change in 1978 on NBC were not pleased with what they saw here:
As an avid TV watcher... I've seen some weird errors in my time... wrong graphics on the screen, tapes obviously starting too early or too late, a slate accidentally airing, too many commercials, someone obviously accidentally hitting the rewind button by mistake, etc. But this? Takes the cake. How could this have been running for as long as 17 minutes without before realizing something went wrong? How?
Perfect case of vintage network fail if I ever saw this one. My online pick of the week!
