Took a brief look at the material in this thread, nearly fell asleep in the seat, felt like the end of an INTL duty day
Seriously, we all get complacent landing on long, dry runways when conditions at VMC. Landing data, as provided to the pilot, from the manufacturer, through the airline and (when operating in anything other than the above conditions) interpreted by both dispatch and the PIC is more art than science. When someone reports that on a cluttered runway, in IMC, with a tailwind (reported when and how much really X vis tail) the landing distance allows only (pick a number) 800 feet runway remaining ; you gotta take that with a grain of salt.
Any braking action report, either "official" or pilot report less than fair should be considered with great doubt. Unless the runway is very long and conditions are good to see before landing no landing with a tailwind should be considered.
Its easy in hindsight to say this but, only though others tragedies can we all re praise our future decisions.
