blaming one another for this, the emerging theory seems to be rebels may have launched the missile perhaps thinking the aircraft was a ukrainian jet. they have taken out a number of ukrainian aircraft recently. given all of the volatility in the region this sort of thing was bound to happen. >> many of us in the military analyst business knew something like this was going to happen. you don't give sophisticated toys to thugs over time expect it to turn out well. at the end of the day putin is the guy responsible for what happened today in my opinion. >> there have been questions about the routing of this aircraft, why in the world were they flying over such a volatile region? why would they route themselves directly over the ukraine. a number of carriers have been doing that. the faa warned u.s. carriers about trying to avoid that area. now all carriers are avoiding ukrainian airspace at all costs. heather? >> doug luzader thank you so
