On a sub-note here, and not intending to offend anyone, but where did this term "airliners" come from? I know it is never used among pilots that fly large jet transports, at least not anytime that I've heard. It is such an odd term to me, I have never been able to get used to it. Sort of like calling an airplane a "bird", which somehow comes across odd to me as well, in this day and age, reminds me of a term they'd have an actor say in a Hollywood movie.
Maybe it's just me, and I have never bothered to comment on this issue before, in writing or in person, but it just occurred to me. Sort of like people using the word "tarmac" like it means something special that is aviation related.
