kelly, good morning. what do we know right now about what might have caused it? >> well we have hints here and there, jose, but we don't know anything definitively as yet. that huey crew was overheard on radio chatter talking about a possible fuel problem before the chopper disappeared, but this morning the task force commander said they could not confirm the cause of the crash yet. at the same time vowing that they would find the cause eventually. a nepalese search team found this crash site. it's in dense forest on a very steep mountain slope at an elevation of 11,000 feet and nepal's defense secretary, excuse me, said that the helicopter was in pieces and that three bodies had been found. so suggesting that there was some catastrophic crash that this helicopter perhaps fell out of the sky. now the task force commander would not confirm that any bodies had been found.
