I respectfully disagree. You quote Abraham Lincoln in your signature; allow me to borrow from him also. During the Civil War, Lincoln had more than a little trouble with a General named McClellan; but he retained him in command even when many others wanted him out. When one Congressman demanded that Lincoln replace him, Lincolln asked him "Who would you have me replace him with?" The congressman replied "Anybody". "Anybody may be fine for you, said Lincoln, "but I must have somebody."
My point is, you can say that if it is not Flt 175, then "anybody" will do. I must needs argue that, like Lincoln, I must have "Somebody"
Thoughtfully yours, hutch
