The opening credits read: "ACKNOWLEDGEMENTS This film concerns the four-day history of a major American scientific crisis. We received the generous help of many people attached to Project Scoop at Vandenberg Air Force Base and the Wildfire Laboratory in Flatrock, Nevada. They encouraged us to tell the story accurately and in detail." "The documents presented here are soon to be made public. They do not in any way jeopardize the national security."
There is no music over the end credits.
