Its clear to see that most all runways are very dirty with tire markings. Are runways ever "cleaned" off per say? I would imagine that its important that the things that are painted white (i.e. center line, distance markers, thresh hold, etc) should obviosly be clearly visible. Does it ever even get to a point where the white needs to be cleaned or even re-painted? If so, how often is this necessary?

It's not the marks that are the problem. When the rubber starts getting built up it does have to be removed. Believe it or not, what you see as mere marks can build to about an inch thick before it must be removed. Not a whole lot of traction on solid rubber.

What I like about those marks is looking at those weird ones whenever I land or T.O. and steer out of the r/w.
Some start very late down the runway, quite abruptly, are very dark and sometimes go zigzagging all over the place... Then I try to imagine how this landing looked like.
At our hub's runway, I saw a new first officer leaving the very first marks on the runway, meters before any other marks, and about 2 meters after where the concrete starts. I was in the plane, powerlessly seated in the jumpseat, and wow, my buttocks kinda hurted a bit for the following hour...
If you're gonna kill those blowers on the flare and the plane is heavy and slow, PLEASE, PULL THE YOKE!!!!!
Looks like I picked the wrong week to quit posting...
