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!!!!!
I'll do my own airline. With Blackjack. And hookers. In fact, forget the airline.
