Search ends for missing after midair collision

After searchers scoured the Pacific ocean for 60 hours, authorities decided to call off the search-and-rescue mission for the nine people who crashed into the ocean after a Coast Gaurd C-130 plane collided with a Marine AH-1 helicopter on Thursday. The conclusion is that no one would have been able to survive this long, that the longest they could have survived was up to 20 hours. the Coast Gaurd had covered 644 miles, without finding a trace of anyone. the Coast Gaurd announced that a memorial service will be held at 11 a.m friday at the Coast Gaurd station in Sacremento.
I feel very bad for the families of the people who died in the accident. Its even worse that none of the bodies were found. I think that it is a very unfornunate, and unpredictable thing to have happen.
