"Alpendohle: Secret Underground WWII Hangar" Topic

"On Tuesday, the German newspaper Bild reported on the discovery by historian Mirko Kühn of a secret underground Nazi aircraft hangar, codenamed Alpendohle, near Altenburg Airport in Thuringia, eastern Germany. Kühn had been researching the mysterious history of the legendary Leinawald forest for over ten years …"

the hangar was 200 meters long, 25 meters wide, and at least five meters high

How tall was the Haunebu?

The ever-reliable Pravda gives some interesting history:

In 1964, the STASI tried to open the hangar, but due to the poisonous gas that came from the dungeon, the work was frozen. In 1996, the Americans made an attempt, and also to no avail. … According to geomagnetic measurements, there is a giant metal object in the hangar … Next to the Alpendohle hangar there is a mass grave of Soviet prisoners of war who were killed by the Nazis shortly before the "sealing" of the hangar

German news has almost identical facts, so maybe Pravda isn't just making stuff up:

Be nice if they gave us more than one photograph. All kinds of things look plausible from a particular position with the sun at just the right angle. Not, truthfully, that that particular photo is very persuasive.

Perfectly willing to believe in an underground hangar at that airfield. The ever-reliable Wikipedia lists underground hangars in a dozen countries, many of which are public knowledge. But I do not believe in one at the location shown on the photo.

Still, that's an opinion, not a confirmed fact. Possibly the crew which excavated that Nazi treasure train near Breslau a few years ago can come and dig this site? Or we can bring in a crew from Oak Island?

As for containing the Amber Chamber, it's actually stored in that big government warehouse shown in the Indiana Jones movies. But they lost the catalog code when they went digital on the records, and have never been able to find it again.

And here's the old airfield under discussion:

But try linking that up with the photo. Our investigator does appreciate that to be an underground hangar, there needs to be a way for aircraft to taxi back and forth between the hangar and the runway, doesn't he?

Not if the aircraft can overcome gravity, like the Haunebu!

True, Oberlindes, but Haunebu aren't deployed adjacent to air bases or runways. They're kept in barns, and the entire roof folds back so they can shoot straight up. Well, except for those in secret Antarctic and Lunar bases, of course. And the Antarctic base was long ago overrun by Shoggoth. Serves the Nazis right for not doing a proper site survey and title search.

Any idea what the official name is, anyway? I mean, it may have been called the Haunebu, but we're talking Nazi Germany, so there are rules. If something flies, it's got a two-letter code identifying the manufacturer, a hyphen, digits to indicate a type and then possibly a letter to designate a model. Otherwise, we'd just be making stuff up.

Oh. Smallest diameter I found on line is 15 meters, but you might want to call the National Air and Space Museum or Area 51 and check.
