What I have always wondered (and I shall probably get beaten up for asking, but never mind), is why some pilots taxi exactly on the centreline, so that the nosewheels go 'thump thump' over the taxiway lights? It can be quite harsh when you are sitting in the vicinity of the nosewheels.
I heard tell that the offset NLG of the Trident was so designed to avoid this, but doubt the story. (The other explanation being that someone in the drawing office put their coffee mug on the blueprint, and smudged it
)
