Hi - This is my first visit to a treasure hunting site. I can't understand why there's no mention of searching for Warbirds in Florida's swamps and lakes. During WW II Florida had 227 airfields dedicated to training pilots and aircrews to fly and to fight. I have documented more than 1,000 major accidents of Warbirds in Florida during the war. Many, many of the crashes were not recovered and sit there waiting to be discovered and recovered. I am now looking at two sites, one in water and one in a swamp. Both were two-engine bombers that were partially recovered at that time but the engines and large parts of the fuselage are still down there. The engines were Pratt & Whitney double Wasps weighing 2,000 pounds each. Are you thinking MD and magnetometer? Should be. Warbirder
