throughout this week we've seen all kinds of information come through. some of it is always falling out. from what i've heard, 45,000 feet is a very difficult altitude for this plane to achieve. >> have to really push it then it would possibly break apart. it might be beyond its maximum altitude. depends on conditions, weight, et cetera. even "the new york times" report where i first saw this indicated that the descent was physically impossible. we know some of this report is erroneous. it may be that the entire thing is erroneous. >> yeah. i would just put -- i agree with that. i would put another angle on it that the farther you get away from the source of radar, the less accurate the altitude deviations are recorded by the radar. so while the radar is attributed to having the plane at 45,000 feet, i heard loss of altitude, 40,000 feet at the moment, which is physically impossible for the airplane. i'd attribute it to the
