3 passengers were taken to a hospital, according to the Indonesian Ministry of Transport (BulePilot:
Lion Air Hard Landing di Juanda, 3 Penumpang Dibawa ke RS ). No further details in the media yet. Exactly how injured they were isn't very relevant, is it. No passengers should need hospitalization after a flight. Clearly this was not a landing you could just walk away from. Says it all.
And that on one of the longer runways in indonesia.
