This particular plane is sentimental to me. Not only did I grow up a big fan of this aircraft, but later in life it was the A-10 that we used to call for close air support when I was a grunt.
There is a false cockpit painted on the bottom of the aircraft. This next photo perfectly displays why that would be confusing to the enemy.
Here's the video I recorded at the air show of the A-10. Please keep in mind I am on crutches looking up, and trying to get the aircraft in frame.
