just a couple of points
leaking while deicing...well, you stuff paper towels in the DV window and no problem
you see, when you deice, the plane isn't pressurized and the windows do leak...but if you know what to do, it won't hurt you.
as to noise...we were the launch customer of the 737 with the CFM56 engines and it turned out that they were noiser than the MD80s we had...as we operated many segments out of Washington National we found we could land later with the MD80 than the 737...(washington has some very strict noise rules)
And anyone that has heard an MD90 takeoff, it stage 4! wow is it quiet.
This type will be a fine freighter and I am glad that they are being converted.
