Another document about the Washington sighting saying that they believe the "flying saucers" to be man made possibly originating in Russia of a post
Horten Brothers design.
The first sighting in May of 47 in Canada.
If this is what it was then the "flying saucer" that was downed in Roswell was covered up because it was a Russian long range, high altitude fighter
and they indeed recovered a body. a body of a Russian test pilot.
The cresent shaped craft flew over the channel over Alaska. from the Russian territories.
This makes sense why there is a cover up.
