You haven’t seen it all until you’ve seen the trailer for “Sky Sharks”

Deep in the ice of the Antarctic, a team of geologists uncover an old Nazi laboratory, still intact, where dark experiments had occurred. Unwittingly the geologists unleash upon the world a top-secret experiment the Germans had been working on – modified sharks that are able to fly, whose riders are genetically mutated, undead super-humans. The only thing that can stop them, and possibly save the world, is a military task force called “Dead Flesh Four” – assembled from reanimated U.S. soldiers who fell in Vietnam.
