joining me now by phone is our paris correspondent, greg keller. greg can you tell us where are you and what is happening at the crash site right now? >> sure. i'm in a village. it's a remote village in the southern alps. it's a good two or three hour drive from any sizable town. we've been en route for about six hours now. just arrived literally minutes ago. this village is a staging area for the search and rescue operation. it's well after dark here now, so the helicopters that have been flying out to the crash scene from here have stopped for the night. so really right now here there's not much going on to mention, really. >> greg, do you have a sense of how big the area of debris is? >> the crash site i'm told is reachable only by helicopter. there are no -- it's off in the mountains. there's not even a road near the site so i'm told it is about ten kilometers of a helicopter ride from the staging area where i'm at, so we cannot see the crash site. we have really no view on that. >> greg keller, thank you. joining me now is alistair jameson. wha
