I choose to believe that The Bell was the object that allegedly crashed in Kecksburg, Pennsylvania in 1965. Because you can imply an absolutely hilarious B-movie plot out of that.
1945. A group of Nazi officers and scientists including Hans Kammler, Martin Bormann, Eva Braun and the preserved-in-a-jar brain of Adolf Hitler board a highly experimental spacetime displacement machine deep in a mine in Poland. Their plan? Using the secret superweapons developed late in the war, they'll travel into the future to create a new Fourth Reich. And amazingly, the Bell and its crew disappear in a flash of light and are never seen again.
Fast forward to 1965. 20 years later is the point our Time Nazis chose, planning to rematerialize their craft on the White House lawn and demand the world surrender to their superior technology and obvious Aryan perfection. But in their haste to depart, Herr Doktor made a tiny mistake in calculating the displacement coordinates ("DUMMKOPF! You did not remember ze leap years!?"), and they miss Washington by about a hundred and fifty miles northwest...and a couple miles vertically. That mistake rather quickly turns into an uncontrolled ballistic reentry somewhere over the Great Lakes.
Meanwhile, the citizens of a small Pennsylvania town are surprised to see a bright object streak through the night sky before plowing into a local patch of forest. NORAD detects the incoming craft, and within hours Kecksburg is crawling with military and NASA personnel. The wreckage is quickly collected by an utterly baffled recovery team, the official story is that nothing was found, and that the locals saw a particularly bright meteor.
But to this day, if you go to Kecksburg and ask around the right places, you might find someone who still remembers that night. They'll say that the military found something out in those woods, and towed it away aboard an unmarked flatbed. Something about the size of a car, covered in a camouflage tarp and shaped like an acorn. Or a bell.
And maybe, just maybe, they'll lean in real close and tell you that the tarp slipped as the truck drove out of town...and swear that between the scorch marks and the scratches on the thing's surface, you could just barely make out the shape of a swastika painted on the side of it.
