Shipwreck hunters have made an unexpected discovery in one of the Great Lakes. The team turned up what is thought to be part of the early days of the Air National Guard in Michigan. Shipwreck hunter David Trotter and his team -- several of them from Mid Michigan -- were searching for a new shipwreck on Lake Huron near Oscoda when they spotted a little something on their sonar. What they found surprised even this group of seasoned searchers. A tiny hit on Trotter's sonar would have been dismissed by less experienced searchers as just junk on the bottom. But the instincts and a bit of curiosity of Trotter and his crew kicked in. Putting divers in the water, they made quite a discovery. It was a relatively intact biplane. The canvas coverings on the wings and fuselage were gone and zebra mussels now coated the frame, but there is no doubt about what it was. "It was a rather old airplane," Trotter said. "It was apparently a biplane and had a very large radial engine reminiscent of planes that would have been in service in the '20s and '30s. "They knew it was old and they also realized it was upside down and it had all indications it was likely to be a military aircraft." The mystery is, where did it come from and how did it end up on the bottom of Lake Huron? From looking at video shot by Trotter's crew, aircraft historian Ralph Roberts of Saginaw believes it's a Douglas 0-38. The Michigan Air National Guard flew 0-38s out of what is now Detroit Metro Airport between 1933 and 1941. Some of the pilots trained at Camp Skeel in Oscoda, which eventually became Wurtsmith Air Force Base. But what caused it to go down in Lake Huron?"
Of course maybe it could be this ?
