>> reporter: the crash site is above us in the mountains. about 7 miles this way and of those, hamper efforts and the fact the whole side is so steep there, the wreckage side is over several hundred meters. that's a concern. access is really only by helicopter. we've seen those helicopters sitting on the ground here throughout the day and the question when daybreaks in the morning, how low is the clouds and will the helicopters be able to fly and get access to the site? the rain has been coming over some of the high mountain passes here has been particularly strong and that if it is falling rain or snow again at the crash site, that is also a worry, anderson. >> obviously, concern for families is have they been able to cover any of their loved ones.
