altitude data that we're getting with a lot of caution. a number of reasons for that, don. the first one is that the evidence we have so far suggests the transformer was turned off or the transponder was off. there is a number of reasons that could happen, i won't go into that now. the bottom line is the transponder gives you position, attitude, speed and information. if that was off, you won't get altitude information from primary radar. primary radar drops off at 125 miles off the coast anyway. secondly, surveillance radar with the transponder drops off at 200 miles. my question on how they're tracking altitude, i find a little bit -- have to be cautious with it. the only way military radar could do that is ground base air defense system which would use a pulse doppler tracking radar. but because of the nature of that, high prf pulse repetition frequency, short wave, which means it is short range. >> so bottom line, of course, what are you saying? >> what i'm saying is i would
