this appears to be a real mystery. at this point, no information in terms where the helicopter may be. we know that search and rescue crews are out on the water. also flying above trying to see if they can spot any wreckage. we know that the last communication from this helicopter happened at 4:40 in the afternoon. thursday, yesterday, there in hawaii. about 40 minutes before that helicopter was supposed to land. this was routine communication. it had been flying over a canyon. keep in mind, these are very routine trips. they do them every day, these touring companies, where they take people above the various canyons and you get to see all the sights of the island. in terms of what's happening now, again, boats in the water seeing if they can spot anything. as we said, weather may have been a factor yesterday. it got pretty stormy, blustering winds, and some rain.
