Welcome back to the our channel for a discussion about how the B-52 is maintained and how the U.S. Air Force plans to keep it flying for another 30 years. I'd be more concerned with the airframe and its age than anything external that can be easily patched, repaired or replaced. And as far as bomb loads the B52's 70,000 pounds total bomb load is made to look small when compared to the bomb load of the Rockwell B1, which can carry 125,000 pounds of bombs. That's why Boeing is the best designer/ builder of aircraft in the world. I worked in the airlines for 45+ years and a good portion of that on the 747. If they're properly maintained they'll last forever. I am amazed at the basic structure of the wings though. Those wing spars must really be something. If anything is going to fail, it's usually those, when talking about something that would make a plane fall out of the sky. Airbus, on the other hand are junk. When my airline first got the A320s, we called them "Hugos with wings". And when they went in for their first heavy maintenance, we had to replace whole seat tracks because unlike Boeing, we couldn't replace just the damaged pieces. They're 20' long!
