#2..I`ve flown the 767-200, 300, and 757-200 as a common catagory. The 757 handles about like an MD 88, 767-200..we called that one "The Dump Truck"..you can imagine how that one flew. 767-300 flys like a big plane, similar to the L1011. Although they flew completely differently, no one that I`ve ever heard of, had any trouble with the various pitch attitudes( after the initial check out and a few landings). The radar altimeters helped a lot on landings, with the other guy calling out the last 100 or so feet going down.
#3..like you, I`ve heard a lot about the MD 11`s lack of tail...you are gonna have to get that answer from one of the freight guys.
