Re: Some things...
I wonder if there are any other aircraft that have seen such long term active service as anything other than museum pieces?
There must be masses of data concerning long term metal fatigue of the airframe and skin, how technological upgrades can be introduced into such an old design. I also wonder whether it would be considered to be airworthy under current regulations. Frankly I had no idea B52s were still in service.
I believe that Congress never 'screws up procurement'. They deliberate, consider all of the relevant information, have sub-committees, reports, hearings, and then vote along party lines.
