Here's a thought experiment; just over a decade ago we celebrated 100 years of manned flight. The enormous advancements from that first rickety aircraft of the Wright Bros. to what is designed to that day are mind boggling. Overlay the notion of the B52 planning to be in service for nearly that same amount of time........................amazing!

Watching a 52 takeoff and the incredible amount of wing movement evident just blows my mind when I wonder about airframe integrity and lifespan of the bird. She's a tough ol' lady.
