Re sbs story
The same story claimed the Turkish Airlines 737 at Amsterdam broke up after overshooting the runway. It never made it to the runway! A plane dropping the way it did from the height it did - effectively straight down - is going to break. All the people interviewed were ex-employees who may or may not have had an axe to grind. I'm sure the relevant authorities would notice a fault given the number of examples but so far no alarm has been raised by the NTSB etc. Simple fact is - planes travelling at high speed off the end of runways tend to get damaged.
