Imagine you're a Rocketdyne engineer in the 60's and one day, some guy walks out of a time warp into your assembly area, pulls out some weird looking cameras, takes a few pictures of your engine, plugs some cables into some unknown equipment, and then, looking bored, sits down and directs his attention to a thin metal and glass slab for a while. When a light changes on the unknown equipment, the guy gets up, sticks his hand inside, and pulls out a tool which takes apart your engine.
That would be magic. You'd think the guy was from the 25th century or something. But no, only 45 years.
