Small planes crashes (and you often here of them being Cessna) unfortunately aren't uncommon..and statistically they have a much greater fatality rate than commercial aircrafts. What happened in the Philly med evac plane is downright crazy just how it fell so quickly after taking off and the story is quite tragic with who was on board as well as hitting a densely populated area
As far as the crash you're talking about if we posted about all the small plane crashes (defined as up to 20 passengers) it'd be multiple crashes per day sadly. I just don't want people, because it's definitely out there, to think all of a sudden there's a rash of plane crashes...in terms of small planes it's common but not something we normally hear about nationally unless something is majorly off or in this case prior crashes putting it in the spotlight.
That said flying in Alaska is super risky, much more than I realized before watching Ice Airport Alaska where they even lost a person who was shown on the show for a while in a fatal plane crash..it's sad none the less about any fatalities or injuries really of a plane crash
