For most individuals, change can be harder with age. Not for the CH-47 Chinook Helicopter -- an aircraft originally designed and built to haul missiles that the U.S. Army no longer uses.
"To see the improvements and what we've done with this aircraft through the years gives me a lot of pride," said Maj. Gen. William "Tim" Crosby, program executive officer for Aviation. "That aircraft was designed to haul something we don't even have anymore, but it is still so valid. It is so versatile at all altitudes, with internal and external loads. It's an outstanding capability."
