"The Ho 229 replica with period-appropriate backdrop in the Northrop Grumman hangar."
Period-appropriate backdrop!
You yanks crack me up, forever caught in visualizing Nazi Germany as if it were a scene from Raiders of the Lost Ark. As if we had nothing better to do than to decorate our aircraft production facilities with swastikas.
All this "if Nazi Germany would have had this or some other secret weapon, it would have won the war"-talk is nonsense. You don't win wars with superior novelty equipment/
Wunderwaffen like the above Ho 229, you win it by producing cheaply, quickly and efficiently good-enough stuff like the Sherman tank, the Mustang, the T-34, Liberty merchant ships etc, having the logistic expertise to bring them to the front AND having enough fuel and gas to run them as well as enough well-fed and medically well-treated soldiers/pilots/sailors to man them. The abundance of penicillin for Allied soldiers did more for the outcome of the war than 200 delta wing Luftwaffe jets ever could have. And even if we would have had that many plus the people and the fuel to fly them, all it would have done at best is perhaps prolong the war a few months for the US to have Little Boy and Fat Man ready in time (your nuclear program was way ahead of what German scientists had, whose heavy water research had pretty much become stuck) to drop them on Berlin. That would have ended the war (and grounded the delta wing jets) real quick.
Cool plane though! But would it have had the technical means to fly stable (an issue with delta wing jets) back in 1944/45? I'd be amazed.
