I just read Martin Van Creveld's The Age of Airpower. It is an excellent history of airships, airplanes, and helicopters. It walks one from early manned airpower (from the Wrights) to today just after the Iraq surge. I am not ready to give Van Creveld the applause because he believes airpower is on the wane, partially due to David Petraeus' wishing to leave most airpower at home in insurgencies. I think they still have their purpose, especially planes such as the A10.
I am in Tucson, where the A10 has a mainstay, so that may influence it. I have also heard about the A10 being significant for close air support with the infantry. I would recommend this book to anyone wanting to learn about the history of airpower.
Do you believe airpower is less necessary for waging warfare? Respond in the comments section or tweet me @jtarb1 on Twitter.
