Thank God, the vulture didn't hit him...

Though I find it a bit un-intelligent, to say that birds crashed into the US Airways plane... The plane crashing into the birds sounds more likely

And this is why I like large planes with 3 ply glass laminate.

It in not the three ply glass (though it helps) that stops them coming through but window heating, without that you would probably have the same effect.

I like the comment on the story!  ;D

I bet the bird doesn't have the guts to do that again!

I don't know, the glass used on heavy/wide bodies, is about 3 inches think, pretty strong.

You are right, thick glass is strong, but when it is hit at speed, something had to give. Best that the window frame does not. Window heating, has two functions, the first is to give the pain a little bit of give in the event of a bird strike, a secondary function of window heating is anti icing.

This story reminds me of the Mythbusters Chicken Cannon episode.

those 'heater elements' are the wire attachment areas... there are very thin wires running down to the other one at the bottom. Same as on your car rear window heater but way more expensive
heard someone say that a Opel Astra heated windscreen is over 1500 euros, while a normal one is just under 400 euros

I am not disagreeing, but no aircraft window that I have ever seen or replaced has what you have described. What is highlighted in the above picture is a small wire element that when heated dissipates heat through the window from that element itself and not via wires as in a car. Also all of the elements are not used at once. Half are spare. When the in use elements fail, instead of replacing the window, you can connect the control wire to the spare element (then enter the defective element into the HIL/MDDR)

On a 737, are they always on? Because our windows are only on as needed by push button. That's why I say it has not effected our windows like you say it does on the 737, we hit birds all the time in the Summer, with the defog off, that's why I don't see how this gives it flex, especial if it is not on 85% of the time to warm the window up during bird strikes.

Looks like I am not making myself clear, and yes on the 737 and A320 it is on all the time. Below are a couple of sites with window heating/bird strike threads.

And here it start at the beginning

7th poster starts the conversation on this subject

I hope this makes what I am trying to say a bit clearer :-/

heater or no heater... those windows arent designed to stop 2 kilo plus birds.

Hitting a fully grown condor or swan (about 12 kilo maximum)with a 737 will probably end up in losing the windows too
