This past weekend I was back out with Innerspace; searching for unfound wrecks in Lake Washington. We were on the water running side scan for pretty close to 8 hours straight on Sunday; looking hard for two bi-plane seaplanes that crashed in the 1920’s south of the 520 bridge. We found a couple targets in the right area but on close review they don’t appear to be airplane parts. We’re planning to go back and make a quick dive on one of the targets just to be sure it isn’t a wing. During the day we did manage to pick up good scans of a few known boat and shipwrecks in the area: SL Dowell, YMS-359, The Bremerton and a burned out hull – but never came across the plane(s) we were looking for.
