Certainly the fatality count will rise, but with modern planes survival tends to be more about escaping the post crash fire. If >50% of the passengers and crew live, I wouldn’t be surprised at all.
Good news is that crashes on landing tend to involve a lot less fuel, which should improve survival chances significantly.
Is he really lucky? Any person taking part in plane crash is unlucky in my view. Also "survived" does not yet mean he is unhurt.
So yeah, if he was in business class, I don't think it'd be crazy for that to boost his survival odds (assuming anyone does survive).
If the pilot is still pulling up when the plane contacts the ground, then you’re probably talking about an extremely high speed crash, where no seat is safe. The types of crashes you need to analyze for seat specific survivability are things like runway excursions and relatively level landings onto fields or bodies of water.
But I wrote that idea very early after the crash. I didn't expect that so many survived a plane crash, even into 4 houses. Now it became clear that many survived. Almost a miracle to me. Very lucky.
My initial idea was some dust in the engines, because that was the very first flight after the lockdown. Bad maintenance.
