Another testament to a remarkable airframe. Another testament to the Air Force's inability to design and develop aircraft to meet mission requirements since the cold war of 60 years ago. These airframes are almost 60 years old and the design is 10 or more years older than that. Now there's speculation they'll be in service for another 20 or 30 years? I met a pilot at Whiteman AFB 20 years ago who survived a mid-air breakup of a B-52. The cause was structural failure from the normal turbulence of refueling. Are we seriously discussing 80-90 year old aircraft? Where's the AF been for the last 50 years?
In the meantime, both the B-52 and B-1 (40 years old) which were designed for trans-continental strategic missions, are being used for tactical air support and "show of force". After 30 years, it's doubtful the B-2 is all that stealthy anymore. Perhaps they'll mothball them like the F-117, which was operational for a relatively short short time. The F-117 replacement, the F-22 has had it's development cut short by the one-size-fits-all F-35. Been down that road before with Robert McNamara in the early 60's.
Yes, I'm a kinda tired after a long day and feeling a bit cranky and cynical this evening. Please drop me off at the curb...
