Eyebrow windows very useful lookout if you are on the outside of the bend during a circling approach.
Wasn't there a long running thread on crabbing 737s a while back?
Quidnunc came up with "The main wheels have 2 - 3 degrees left/right play in them, so if the a/c lands in a cross wind the mains may be out at their limit. When taxying it then appears that the a/c is crabbing. The wheels are straight straight down the taxy way, but the fuselage looks (and is) a couple of degrees out of alignment."
Sounds feasible
