The props give it the radar signature of a building. And it can be heard at cruise altitude by submarine listeners.
It would be useless for dropping bombs overhead but it doesn’t have to. The bear can be loaded with cruise missiles and hit from 1000 miles away with GPS accuracy.
actually, i think it is PERFECT for dropping bombs or nukes from overhead. It apparently got right up the coast, or even overland, of the UK without any resistance. Bet it could skirt our coast the same. Bet it could get within 50 miles of DC without any resistance. And do damage before our skirts running the military could get their mouths off obamas tool to respond.
