The A-10 (Warthog) is a unique looking, pretty airplane, though in kind of a butt-ugly way.
It's a sub-sonic, ground troops support aircraft designed to have great maneuverability at low speeds and altitude, so it doesn't need be as sleek as fighter planes.
Grunts love seeing an A-10 that is strafing the opposition or plugging the opposition's tanks with uranium-depleted rounds from that 30 mm canon.
Because they are exposed to ground fire Hawg drivers sit in a titanium armor "bathtub" that can defeat up to 23 mm canon fire, and some 57 mm rounds. Plus interior surfaces of the tub directly exposed to the pilot are covered by a multi-layer nylon
spall shield to protect against shell fragmentation.
Having lived in Tucson for a lot of years I saw a lot of A-10's, because Davis-Monthan AFB is the main A-10 training base.
At one point on a training misson out of DM, an A-10 disappeared. It was a pretty big news story for a while.

Back in the day we pretty regularly saw U-2s too.
