Black nontransparent glass (Cycles) I am modeling plane and I don't want to model a cockpit so I want to use black windows which will reflect a lot of light but you can't see thought. 

Currently I just use Glossy BSDF (GGX) with almost black color (0.01, 0.01, 0.01) and Rougness 0.015 but it don't look quite right. It lacks glass shine and looks too matt.

Edit:

Here is my simplified blend file:



Also here is what i want. Glass on this tie fighter is blackish and it looks like glass. In my blend file it looks more like plastic.



One more thing i noticed is when light reflect from glass whole glass section reflect same amount of light. It can be seen on tie fighter example above.
You can use a glossy/diffuse mix with the fresnel or layer weight node as the mix factor. This is basically the same thing as the glass shader, but without any transmission. You can actually remove the diffuse shader entirely and leave the first input blank if you want. It'll be a bit less realistic but you get a darker black.
