So true on the sound. I can still remember when I was a kid (55 yrs ago?) playing in the yard with a friend. We heard a distant rumble. As it got louder and louder we began to wonder whether we should run, take cover, hide, ???? Then we saw it coming toward us and we were mesmerized. Flying at very low altitude and passed directly over us. Never saw or heard anything like it before or since. Certainly impressed us young kids then and I am sure it would this old(er) man today.
I think it was the B36 that went on display at the old Great Southwest International Airport of Ft Worth. It sat out there in front for many years before they eliminated that airport for the new DFW airport. Don't know where it finally went to.
Edit: after reading further it was moved to the Pima Air and Space Museum
B36 at GSW
