Couple of question regarding aircraft with glass noses.

Are there any concerns over the integrity of this type of nose as compared to traditional materials? (speed limitations, corrosion, cracking. etc.)

Where, if equipped, is the weather radar housed?

RE: Glass-Nose't

Structural integrity is probably better than most non-glazed noses. Those are made of plastic (well, fiberglass) usually, glass noses are have a sturdy metal frame.
Flying through heavy dust (sandstorm, volcanic ash clouds) I imagine the glass might suffer more than metal would. But such conditions are not all that common and can usually be avoided (plus a sandblasted nose doesn't impact safety).

Tu-134s are about as fast as or faster than DC-9s.
The RADAR is in the housing under the fuselage (if fitted, early models didn't have one).

The glass nose used to house a navigator who would double as a spy (many Aeroflot aircraft got 'lost' near NATO military installations...) and in times of war as a gunner (the front element can be replaced with another one with a machine gun in early models).
