is happening. >> and you know -- i have been contemplating this for two days now, what has been bothering me about this fuel. richard and i had a brief conversation this afternoon. and i think the information is being conveyed slightly in error from the standpoint i don't -- the bottom line was i saw this fuel calculation that i looked on performance charts confirmed by a very credible boeing source that has the same performance charts and saw that the airplane would burn slightly more fuel if we contend that the airplane descended to 20,000 feet. that being said, because of the thicker air it is going to go slower and therefore not get as far when it runs out of fuel. that is my contention, i think they're going to the right place for the wrong reasons, if indeed the airplane went down to 12,000 feet.
