Most of those were contemporary cars for people working in the factory when it was built.

“it is expected to serve into the 2040s”
The USAF will have new B-52s built from the inside out by that time.
From the “Report of the Defense Science Board Task Force on B-52 Re-Engining”:
“The B-52H airframe life is estimated at between 32,500 and 37,500 airframe hours based on traditional mission profiles. The upper wing surface is the limiting structural member. The task force consulted with the USAF and Boeing to reaffirm this estimate. As of 1999 the average airframe had 14,700 flight hours. Re-examining past data in light of emerging mission profiles, both the System Program Office and the task force judge that the airframe life is greater than the current estimate.”

37,500 hours is less than half of what you see out of an average airliner. Now, low level will be harder on a plane, but most of the B-52s life isn't that much different.

That is valid point. They definitely aren’t running air routes daily like an airliner, nor are we in the Cold War or Vietnam.
