Welcome back to the our channel to witness how the U.S. Air Force maintains and tests its aircraft jet engines. Amazing. I can't believe the changes in aviation I've witnessed in my lifetime and I'm sure there's far more advanves going on that we don't even know about. If I were an adversary, I would be more afraid of the Bone instead of the stealth bomber. That Bone is the most impressive bomber we've ever produced. If you see it or hear it after it crosses your airspace, you're already dead. Nasty, nasty plane. It's DNA can be traced back to My Navy's Vigilante Carrier Based Bomber. I see the Russian and Chinese copies of our B1-B and they're a joke. You can't copy the best aviation training, ground crews and Logistics in the World. The B1 needs upgraded engines it needs to be faster.
