Not just crash here either. Back in post 8, I noted this amazing co-incidence.
Lets say for kicks that an Alien craft did crash in Roswell, and that is fact, not question. The debris as you can see above does not have an panels, no knobs buttons of handles of any kind, there are no engines, no technology, not even an alien resistor, nothing. What we do have described is some waxed paper, rubber backed foil, and balsa wood. (see above) Now the Roswell people did say these were not foil, balsa wood and waxed paper, they said it looked exactly like the stuff, but exhibited different properties, lik the foil folded back, the wood did not burn, they could not dent the metal. Right? But in all cases, it is agreed that the alien materials looked exactly like the much weaker earth counterparts.
Now for the odds. Imagine this.
These aliens not only live on a planet in some distant part of the galaxy (presumably they come form the Milky Way - according to the more exotic version of the tale) but these very aliens just happen to have materials that look just like Balas Wood, foil and waxed paper. That is amazing in itself I have to say, but this goes further. Not only do these aliens happen to have materials that look like weak materials here on earth, but they made a spaceship out of just those component's, nothing at all that looks exotic, everything has a visual equal here on our earth, then they fly is across space, crash it on one of the most predicable weather patterns in the entire solar system, but not just on the planet, but in that tiny corner where you guessed it, the Military just happens to have a covert project going that utilises foil, balsa wood and waxed paper. And that the items look so similar, to the naked eye they cannot be separated, but when you try to manipulate them the alien tech becomes apparent.
How is that for amazing co-incidence? I often wonder what the odds would be, I would imagine 1 in the billions.
