The crew of Croatian, German and Italian divers found two US plane wrecks near the island of Vis, Croatia. B-24 and a life saving seaplane (107m and 94m). Both were shot down in 1944. Another find in the vicinity of Vis was a Greek steamboat that hit the rock near island of Brusnik 84 years ago. It was a transport boat which carried coal. It was found on the depth of 73m. Unfortunately the link is in Croatian but there's a nice video showing the wrecks. http://magazin.hrt.hr/354021/u-podmorju-oko-visa-otkrivene-olupine-parobroda-i-dvaju-zrakoplova
Unfortunately this is the only information they provided. The wrecks will be probably further investigated.
