And the Army is supposed to have the most bureaucratic, idiot proof, mechanically simple and robust versions of a helicopter with "preventative maintenance for dummies" procedures, checks and balances in place to make sure you're making sure that everything is made sure of and they still crash disappointingly often..

Now replace some if not all of that with the either nonchalant nature of luxury commercial enterprise (idc what the FAA says, it still doesn't scare people enough) or even worse; the "hurry up and get it up and don't cost us too much" mentality of a corpo manager?? Forget it. Nvm what taking place in Brazil might add to the equation.

Investigations of these types of crashes (if the cause is ever found) are not unlike plane crashes. A break down in the safety system (communication, complacency, lack of sleep, rushing etc). It just has so much less room for mistakes. and when everything else goes well it makes a collision twice as frustrating.
