>> sure, let's talk about that for a second. air bus, we have of the a 320, this is a work horse for air bus, there is 6500 of these built. and of those 20, losses. and a safe airplane. it was not built to have a long life. and so it was not meant to go in service past 20 years and i am speculating of the numbers. it was really not an airplane built to last a long time. unlike boeing. we have boeing aircraft that are flying and nearly 50 years old and boeing using aluminum and built their planes like a tank for a lack of a better word. air bus, they aren't designed to go past 25 years and so the age of the airplane does speak clearly and could add to again,
