Originally posted by tim60 Something that puzzles me about the B52 being flown through to geriatricity is: if it is so successful, why don't they go back to factory and ask for a few more to be run off using the original drawings, and then they will be able to keep flying them without the problems of metal fatigue etc. Also, would save a lo of money on the overhead of designing a new model.
The tooling is long gone, destroyed after the last plane rolled out of the hangar. The hangar is likely long gone too.
So, to restart production, a place would have to be built, tooling created, mechanics ired and trained. Of course production methods, materials and techniques have changed some since then, so the first plane would have to be used for static test, the second would be a flight test unit, and then the customer planes built.
That all costs money.
It wouldn't make any sense to build a copy of a 60 year old design.
