If you aviation geniuses have it all figured out that an old decrepit DC-8 / 707of whatever model / vintage is any better than a 757 F economically , then perhaps you should put an application in to AIG , Citi , UBS , or any of these other institutions that could use your accounting skills. I`m sure you could convince both Boeing and Airbus to restart up the line...Quit living in the past. Nostalgia doesn`t pay , economics do. These a/c belong in a museum.
