I had a B-17 fly right over my house at about 500-1000 feet a few years back...I was working in my backyard, and heard that sound, and began looking around and there it was...
All aviation nuts know the sound of those large reciprocating engines...especially when there are more than one!
I think it may have been flying to Hanscom AFB...I am right in the flight path!
I had that same experience here in southern NJ a few years ago. A B-17 flew over on it’s way to a local airfield as part of a traveling tour. I heard the throaty roar of those Pratt& Whitney’s and there is was. What a sight. A few months later it was a B-24. I went to the show and I couldn’t believe how cramped the inside of both those planes were. There wasn’t anywhere in either plane you could stand upright. The bomb bay of the B-24 offered a little bit of an ability to at least straighten up a bit but the cat walk through the bomb bay was only about eight inches wide with a ‘’railing’’ about waist level. That was the only thing between you and the Earth. My God, those men, kids really had guts.
