flown to try to determine where it might have ended up. for example, an aircraft has a very small fuel burn at high altitude. if the aircraft was flying at 40,000 the hit would go a long way. thusly if it was down at 12,000 feet, it would not go so far. we don't know what altitude the aircraft was traveling at. we don't really know wat speed it was going at the then obviously we have some information that gives us some idea of the speech. so it is a very inexact science at the moment. would you care to say anymore? >> certainly. while you are seeing all the evidence on the ground here, in
