Different types of technology. and there is the idea that let's say that all different commercial airlines were using this type of data. they weren't just using it if the plane veered off. this would be a lot. this could potentially cause satellite interference. and this specific case, they like to say it's not used unless the plane veers off. if this technology were being use liezed by airplanes, this is something o to look at. >> when you have accidents like this, there are fixes that come afterwards. they will have to look at something. a major airliner lost for 14 days. thanks very much to...
