Warning. Heard people say on Reddit to NOT listen to that audio.
Yeah will have to wait a year or two to find out the cause.
I'll just say I wonder why they flew in that weather system at all. From watching too many accidents on YT I am guessing with private aviation there is more pressure to get it done.
On flight radar where I live if there is a fraction of the thunder storms the sky is a ghost town and they will delay departures from other airports say 1hr flight away to wait it out.
