Correct me if I am wrong, but I would have thought that transitioning from turbo props to jets would have made them land deep?
I guess I wasn't very specific, there is not only one pit-fall as a result of them transitioning from props to jets.
I was comparing it to the Rio Sul EMB crash in which the fuselage cracked in half just behind the main gear mountings. It was a case of getting too slow in a swept wing aircraft and developing a high rate of sink at an altitude which affords no room for recovery.
Then again, maybe they just aimed at the wrong place.
