Tom,

Speaking strictly "off the cuff here" as I have yet to do any testing, and have not been into the local glass shops or websites yet.

My thought to exiting through one of the film covered windows would be to use a "sharp" of some type, anything ranging from handy office scissors, EDC, corner of metal drawers etc. to try and scribe a circle or several arcs or lines to form a polygon of some sort, then attempt the center punch methodology. Once the smaller opening is available, other objects could be used to lever / wedge / pry / curse / push / pull / catch breath / use CO2 fire extinguisher if available / foiled again heavy duty exhortatoins if no CO2 then a regular ABC as a blunt instrument to make my way through the laminated inside pane then the outside pane.

I concur with your post and that there are ways to do these (weird to non ETS folks) type of things.

At first glance, (pun intended) it would be a pain. However, the subject is a valid one, and I will quietly peruse it a bit more on the research side. This will take time though.

Regards,
