Radar information? >> possibly. i'm surprised we haven't heard more from them. if you're within 160, maybe even 200 miles from land, a civilian or possibly military radar should be able to pick you up at that range. if you're farther out than that, it's not likely that the air traffic control radar will pick you up. but the difference between vietnamese and malaysian air space is more of an administrative line than it is a technical line in the sand. >> john, i want to ask you about the many being equipped with four emergency locator transmitters. they were not picked up. they were supposed to...
