Greetings,
It is really sad and i'm sorry for the family of
those who died in the crash for thier loss.
The accident had happened for whatever reason.
The most important thing is to have RESPECT for
all the individuals and LEARN from the actual cause
to avoid such things in the future.
Accidents happen either in simple or complicated
aircraft, day, night, VFR, IFR or even on ground.
Rules were made and updated as experts see
them necessary. So, try to follow the rules as much
as you can
..
Fly safe
