Co-piolit brakes window to keep cabin from filling with smoke
He opened it, if anything. Those windows are extremely hard to break. They are panes of laminated glass.
The link I posted had the co-pilot breaking the window in it. The article has since been updated with more info and no longer suggests the co-pilot broke the window, just that it is now broken. Sorry if that was incorrect. John.

You could not break the glass of a cockpit window not matter how hard you tried. Even with an axe you'd be lucky to break it. Besides, there'd be no need to -- the side windscreens of a 757 can be opened manually.
Just raw speculation, of course, but it sounds to me like an errant window heat system that 1. cracked the glass, and 2. caused the smoke. Not an unheard of malfunction.

I guarantee you that I could go from being strapped in the pilot seat, to being on the tarmac lighting a cigar in less than one minute (holding the ax). Heck.....it's just an commercial airliner, not an armoured car.
BTW, I have seen a few photos, since being a member here, of large birdstrikes that very nearly penetrated the glass. Dude.....if a bony bag of biomass nearly makes it through......the tempered edge of that crash ax should go right through first attempt.
You cannot give the ax a Barbara Billingsly swing and expect to have it do it's job. You need to be serious about egress to make it work.
The "Crash" Ax
And finally for this round-up, most business turbine aircraft and all airliners come with a tool with the pessimistic name, "Crash" ax – a hammer-like all-in-one tool designed to cut seat belts, break out windows or shear through metal. This safety tool is arguably the oldest in aviation.
While pilots debate the effectiveness of these tools – great for prying back interior panels, not so great for cutting through metal – for the pilot who has needed one to sever an imprisoning seat belt and shoulder harness, then shatter the cockpit window, there’s seldom any controversy.
The relatively low-tech crash ax usually resides on the flight deck, though some aircraft carry more than one.
As a hedge, carrying a second in the passenger cabin and briefing passengers on its location is never a bad bet.
Modern application use more plastics as the protection/cost has increased enough to outweigh the downsides of plastics.
I wouldn't be surprised if the only difference between airplane cockpit windows and lower level armor glass is that the cockpit windows have heaters in them to keep them from breaking at cruise altitude.

Quoting UAL Bagsmasher (Reply 23): HAWK21M, I've seen shattered windscreens as a result of a controller failure on our aircraft in the past.
When you mean "Shatter" Do you mean crumble to pieces & fallen glass.......Thats what I mean.
Never happened on a B737 or B757 though.
WHCU malfunctions leads to cracked windshield that still stays in place.
