Most people out there would act the same way, just observe, it's a form of shock, oh what do I do scenario?. Takes a particular kind of person to risk their own lives jumping into the unknown to rescue someone, the bystanders cannot be in anyway help responsible. I've been a part of an EMS team for years, it's no picnic it's very confronting!
The pilot should not have been there in the first place, his family now suffer the consequences of his irresponsible actions, I feel for them.
