air space, if you will, could that have been literally flying under radar? >> well, it's a little confusing to me, wolf, because the terrain in malaysia offers up several peaks at about 7,000 feet above sea level. so if in fact he was flying at 4,000 feet above sea level, it's very likely he would have encountered what we call cumulus granite, which is what we call it in the pilot business which is a mountain. so an altitude above ground or above sea level, it's 7,000 feet, plus 4,000, which puts us at the 11,000 or 12,000, which we've already reported. these numbers have been very confusing to me and i'm told the malaysian military radar is not very accurate. >> what's your analysis of that, if in fact that plane went down to 4,000 or 5,000 feet, peter,
