Here's the press release direct from Boeing:
Boeing Next-Generation 737 Gets a Face-Lift
SEATTLE, Jan. 26, 2005 -- Boeing [NYSE:BA] this week rolled out its first 737 without eyebrow windows, the four small windows above the front windshield. In the past the eyebrow windows helped provide better crew visibility, but today's advanced navigation systems have made those windows obsolete. The design change reduces airplane weight by 20 pounds and eliminates approximately 300 hours of periodic inspections per airplane. Retrofit kits to cover eyebrow windows will be available mid-2006 for the in-service 737 fleet.

Speaking of the 727 and sextants...
the 727 had a map light in the eyebrow window which had a convex lens on the end of it. If you turned the light all the way down to where there was the faintest glow, you could tell a F/A that it was a telescope. I had more than one F/A swear that they could see stars through it. All I could see was a pair of celestial bodies while the engineer was stuck looking at Uranus.
Point is, the view is what you make it.

, hard to explain hot dog guts frozen to the dish though, ( I can neither confirm nor deny whether someone I knew in a previous life told me this story over a few beers one night...

What some of them have -- KC-135s, EC-135s, RC-135s, some other -135s -- or had -- B-727s, B747s -- is/was a hole in the top of the fuselage near the back of the cockpit, and a mount beneath that hole that accepts a persicopic sextant. The mount seals the hole when the sextant is not in use, and it holds the sextant in place when mounted. It holds it both in the retracted position (nothing sticking out of the airplane), and in the extended position -- to "shoot" celestial bodies. THe hole is 1.375" in diameter -- slightly smaller than the diameter of a large chicken egg. That doesn't mean a large chicken egg wouldn't fit through it, though.
Vacuuming with the sextant port was frowned on after debris kept getting lodged in the Q inlet, which affected rudder feel. My favorite party trick involved a roll of toilet paper. Insert wooden pencil through cardboard tube, and hang on to both ends of the pencil. Open sextant port and put end of roll up to the hole. As long as nothing gets caught and it's allowed to unroll freely, it takes about 3 seconds for a full roll to unwind and exit the airplane.

Getting some celestial nav instruction from the Navigator helped to pass the time on long night flights. About all I remember now is "follow the arc to Arcturus, and speed on to Spica." In earlier days, pilots could learn a lot from the Flight Engineer and Radio Operator too. Automation, for all its benefits, has taken away part of our aviation heritage.
