Forty seems about right for a wing commander in peacetime. There has to be some military pilots on FR to explain.
From a retired (former) Army paratrooper I can assure there are many pilots and crew up to forty years old. When one considers an officer does not enter “actively” into the Active Duty force until graduation college, age 22-24 is about right for a 01/2LT - given most do 20-years active duty works out the math, even given that a officers date of service is actually when they join ROTC or the Service Academy, this LTC probably has 22-years of service. National Guard, Active Reserves (remember Pres. Bush in TX) are older and ready to fill the ranks in Korea or elsewhere based on Op Plans that detail even the tail number of the aircraft due into conflict up to 90 days plus given a conflict....
