Which part of a plane is the safest?(Front, back, etc)

Planes are really safe, there's not really any part that's much safer than the rest of the plane. Statistically, I suppose, the rear of the plane has the highest survival rate in crashes, but the chances of anything happening is so minuscule you really don't need to worry.

I would say probably in the middle part of the plane, but I guess all the rest of the parts are seguro too.

i dont know, probably the middle of it.
