As I was walking along the beach, a plane crashed.
I said "It is not a happy day for those people."
Then a man in a white lab coat appeared, carrying an oscilliscope and a mass spectromiter.
"What are those things?", I asked, for I did not know what they were when I saw them then.
He told me what they were, then vanished.
...Well, if you can call walking till he dissappeared behind a large fence vanishing.
I walked on.
