An EZY 737-300 more so than the 700 has windows on the doors which are too high for a crew to see out off when sat in a crew seat. What crew forget is that when checking for hazards (should you have to open the door or blow a slide) you would be standing up not seated.
With alot of experience of flying on the 737 (various types) I have observed that windows do freeze over but not fully and should it happen, you would obvioiusly at least crack the door and determine the best action from there.
I would say that crew have this observation of windows being out of place because they like to be nosy on take off and landing and have a good look out of the window to see what they are missing.
Remember the real saftey implications that you were taught in SEP. Telling your company that your view (or what you expect your view/opinion to be) isnt to your liking, is not an SEP issue. Boeing would not exist if they were getting it wrong.
767, and 757 windows do indeed have a magnifier window from which you can see oiut of more than adequatly. And maybe they should be fitted to the 737 too.
