Some interesting observations there Tim, etc. I finally remember where I heard a reference to the Tunguska event recently and it was from the film "Ghostbusters" of all places, lol. Interesting that in the movie Dan Aykroyd's character mentions it as having taken place in 1909 rather than 1908. I wonder why...
Dr Ray Stantz: Are you okay?
Louis: Who are you guys?
Dr Ray Stantz: We're the Ghostbusters.
Louis: Who does your taxes?
Dr Ray Stantz: You know, Mr. Tully, you are a most fortunate individual.
Louis: I know!
Dr Ray Stantz: You have been a participant in the biggest inter-dimensional cross rip since the Tunguska blast of 1909!
Louis: Felt great.
Dr. Egon Spengler: We'd like to get a sample of your brain tissue.
Louis: Okay.
