I guess you either haven't flown much or never looked out the window when you did fly.
I can see landmarks from miles away. Landmarks that aren't nearly as tall or easily recognizable as the WTC towers were. By the way, do you really think that modern aircraft pilots rely only on line of sight reckoning to know where they are?
but we are still talking about pilots that are not fit to fly the planes
We are? Since when?
The hijackers had trained. This wasn't their first time ever in a cockpit of that type. The people training said they weren't fit to land the plane but that wasn't their goal. They were certainly capable of steering it in flight.
