Kinda off yet still on topic, there was a guest on the Art Bell Coast to Coast AM radio talk show who was on to discuss aliens and saucers.
Arts guest had a website featuring various saucers. One of the pictures on his site was a grainy picture of the Invaders saucer with people standing around it and claimed it to be a genuine picture of a Nazi experimental aircraft. The people standing around the alleged Nazi saucer were standing by incredibly coincidance, in the same postures as the figures that came with the kit. When I emailed the guy sending pictures of the Invaders kit I got a reply saying that the Invaders TV show probably found the same alleged Nazi saucer picture during their research and used for inspiration on their design.
If I find that site I'll post a link. Its crazy.
