Has A&T ever done any saltwater recoveries? I wonder if there is any difference in the way you do a recovery besides accounting for the condition of the aircraft.

very very good question!! salt water recoveries are totally different in preparation than fresh water!!
Very Very big difference. Salts create a chemical reaction with the metals. It is not simply a matter of washing away the salt. The salt reactions need to be arrested and in the absence of air, which exacerbates the situation. It is my understanding that much of this aresting process needs to be done immediately, which the ship is still at sea.
As I said in an earlier message, it is possible that more damage cane be done in two weeks of exposure to atmospheric oyygen as was done in sixty years of salt water immersion with dissolved oxygen.
This all assumes that the goal is a restored aircraft, rather than a rusted wreck in an "as is" diorama. Gettig a saltwater immersed aircraft to restored status would be much more difficult than with the Lake Michigan recoveries. Indeed, good restorations from salt water wrecks have been very seldom accomplished; the F3F off California is an example that comes to mind, and one has to ask how much of the aircraft now on display at NMNA is original.
