Gives me a "warm fuzzy"... I have a soft spot for 'Hogs:
When the A-10's were being built, I was fortunate enough to be around the assembly line (my dad was on engineering staff). Also watched the aircraft take off on their test flights and handover flights.
Unfortunately, those factory floors have been silent, since the last A-10 rolled off then line in '82. Fairchild-Republic is no more. I, coincidently, work across the airport, from the factory site. There are some businesses leasing space there, but the "heydays" are long gone...

Watching live fire from these beasts is something else, too!
You hear the "Braaappp" of the gunfiring, followed by the solid, rapid "Whoompp, Whoompp, Whoompp" of the rounds striking target. Scary, just to listen to.
