The funny thing is, scrap metal guys hate airplanes, you actually have to cut the rivet lines out to get a good price for the aluminum. I was using a multi cutter blade on a 4" pneumatic angle grinder to cut the clean metal panels out from between the rivet lines otherwise it sold for the same as the riveted aluminum that was half the money. Since the plane in question was a Cessna 411, that added up to a fair amount of value, and cutting. Took me a week and a half to tear it down and get it cut up.
