We are talking about WHICH pane is broken, not whether to take off with a broken window.
If it is the inner pane, touching it will confirm this.
If it is the outer pane you may be able to tell looking at the edges or where the wipers touch.
Anyone have a better answer (to the question)?
Oh, and put your oxy mask on before dumping the cabin.
Oh, and don't dump the cabin if you don't have to.
