The B-29 "Doc" that is here visiting this weekend just buzzed the house........doesn't have the original engines, but still sounded pretty sweet..........when I lived in England we were only 20 air miles from RAF Duxford where the "Battle of Britain memorial flight " was based......we would get buzzed by Spitfires' , Hurricanes, Me-109 , Heinkles and the last flying Lancaster all the time....the sound of those Merlin engines would give you goose bumps
