up here straight and level flight for about three or four minutes. and then all of a sudden the drop-off and the steady decline and the steady amount of air speed as well until the very last and final minutes, just very curious as to why something else didn't take place, especially a mayday call or something. and i know it's -- i get it. but you get on the radio and say something, don't you? what we could see is the cloud cover covering the ground they honestly had no idea where the ground was. and i just don't understand how this doesn't go out -- david, tell me if the plane's engines are out and they don't have any power, can this plane fly for 102 miles? >> well actually it can. but i don't think that's the situation here. as you pointed out, the air speed continued to maintain the same. you can do that by putting the nose down and continuing that descent and controlling that descent. it's a very controlled descent. but it has a good glide ratio,
