what do you read into that from a pilot point of view? well, my initial guess is that their altitude probably was maybe 10,000 feet lower. you can fly at a much higher mach number in the mid 20,000 foot range than you can in the mid 30,000 foot range. however, your fuel consume, goes up significantly. we do know how long the airplane flew approximately based on the pings. so that s going to give us an area. frankly, piers, i m pretty excited to hear they re further narrowing the search area down. let s face it. until we get a ship with a helicopter or a small boat to pick something out of the water, to get us our first point to start calculating backwards, we re not going to find the wreckage on the bottom of the ocean. and the key here to solve this is to get to the wreckage on the bottom. far bigger deal than just another airplane flying ahead at 3,000 feet. it seems to me a pretty dramatic development now in this search. we ll come back after the break, go through it again. and
