Ya, thousands of aircraft, some at literally hundreds of millions of dollars each (F16 $19 million, C130 $62 million, C5A $168 million, B1 bomber $283 million, Stealth bomber $1 billion). Our tour guide had a spiel about how they preserve the equipment and harvest spare parts, and they save $17.00 for every $1.00 of parts recovered. But it didn't look like a "for profit" operation to me. Very impressive though.
