I saw a documentary that said Hitler believed in the ancient Lost Ark of the Covenant and even sent a group of special Raider forces to Egypt to capture it. These Raiders were initially successful but were ultimately thwarted when the Ark exploded upon being opened, killing all but 2 American archaelogists who'd set the trap. The Ark and its contents were never seen again. The male archaeologist was seen a few more times but no one knows what happened to the woman, who was apparently his girlfriend.
