I you believe this because.....?
Just asking. If Congress seems to be the driving force behind acquiring them, and I'm assuming the military is disinterested in building up their inventory, why would you want them to have more?
I can understand if you have a financial interest in their production (stock, employment, etc.). These things are not cheap to maintain, and perhaps the military would rather their budget go somewhere else.
Just running through the possibilities if the AF isn't sold on more of them.
I want to have more C-17s to meet our commitments overseas especially in Iraq and Afghanistan. If there is a war in Korea we will need to transport men and material from Japan to South Korea.
Given a choice, talk to the staffs andf the flyers, the AF choses C-17’s, hands down. It is the political over-lay that is keeping the C-5's.
