there is some confusion...American Airlines did operate the BAC 1-11 and called it something else like the BAC 400 or seomthing like that.
Aleghany Airlines operated the BAC1-11 for quite awhile including under the USAIR Livery. I could have bid the BAC1-11 but took the DC9 instead. Big stove pipe like noise reduction devices were placed on the plane near the end of its service life. Indeed, all the old guys Knew that BAC was so ingrained into the airline that the multiple choice exams were always BAC in their choice: example..answer 1 = B, Answer 2 = A, Answer 3 = C and then repeating.
Does the Handley Page and later BAE Jetstream regional airliner count????? I flew the Original Jetstream for awhile , even the one used in the Bond film.
good luck you guys.
