Seven marines and four aircrew were missing Wednesday after the crash of a military helicopter along the Florida coast. Bodily remains have been washed ashore on the Air Force base in Eglin, Florida, on the Gulf of Mexico, a military spokeswoman told dpa. Wreckage from the UH-60 Black Hawk helicopter has also washed ashore. The search mission was hampered by heavy fog along the coast. Two helicopters had set off after nightfall Tuesday for a training flight that involved troops jumping into the water and making their way to land. Only one returned safely from the exercise.
