My understanding is the -800 is also significantly faster across the fence compared to the A32x, and even the 737-classic, so that would provide and extra margin for pilot error in the decision to land/go-around for deep landings and floats on marginal runways
yes, the -800 has a higher average ref speed. It has been referred to as being ‘slippery’ however with over 8K hours on type I can say with a reasonable amount of conviction that this is due to it being mishandled/mismanaged. Regardless of aircraft type, there is no excuse for landing any aircraft almost 2/3rds into a 3km runway in wet conditions with a tailwind component that’s well beyond certification limitations (unless you were on fire or had a thimble full of fuel remaining). If that’s what has happened then this is regrettably another case of an avoidable runway excursion that has led to fatalities.
