So, do we know for sure yet, whether the aircraft flew again after the "4.6g" touchdown? Is there some kind of incident report out yet?
IGh - the go-around upsets you're referring to were on an Airbus A300. The A320 types wouldn't have behaved the same way, although mode-confusion/vestibular disorientation is a factor in at least three 320 go-around accidents - two in the Ukraine, (Black Sea was one?) and Gulfair at Bahrain if I recall.
