I was pointing to your statement that runway length is influenced by passenger comfort.
It is not.
As for your comments about what is possible.....
Certainly.
Hell, I knew a captain for Eastern that regularly landed a 737 and turned off at an intersection that was not easy to do in a Bonanza.
If he had lost an engine and had to blow and go, he would have created a news event and a huge mess.
Someone turned him in for it and he got a lengthy vacation with no pay.
Many years later he killed himself and the son of a friend of mine while demonstrating his superior ability.
And of course there are the real pros that they send in to fly big iron off of the 3500 ft. runways that the crew mistook for their destination.
But none of that has anything to do with passenger comfort.
If a plane load of passengers has to land on a short runway the breaking and engine noise is uncomfortable for them.
Ask any Freeper who flew into St Thomas on American Airlines jets before they lengthened the runway. If you had a book on the seat next to you it would come sliding off and hit the seat ahead ,you would get jammed forward against your seatbelt. . St Thomas definaely needed a longer runway.- Tom
On April 27, 1976, American Airlines Flight 625 ran off the end of the runway, killing 37 of the 88 on board the aircraft. Following the crash, American Airlines suspended jet service, to the airport, using propliners until the runway was rebuilt to its present length.
