Did you know that there is not one original rivet on any currently active B52 that was there when it was produced? Every part has been replaced by spares over the last 40 years..and yep, they'll be around another 40..when you enter my office at home, you are greeted with a 'Nam verison 1/72 scale B52 I made about 10 years ago. Besides the Black Widow, the B52 is my 2nd favorite A/C.(not that you care...)
