I personally do not think that our Military especially our military teams that preform for the civilian public would use subpar parts due to budget cuts. I was a aircraft mechanic in both fighter and bomber AFSC's as they were in the early 80' all aircraft get the top of the line parts at no expense. Yes the planes are dated but upon inspection no one would without experience would know the difference, the B52 dates back to the mid 50's and are among the top bombers of today, they were considered to be replaced by the B1 but that was rejected because of it's excellent performance reports of todays standard that really eliminates the subject of age. The accidents were just coincidence that just happened the same day and could not have been foreseen.
