This article has been floating around for a while, and I could have sworn there was a thread on that here. A search didn't find one..
Anywho, KDCA and KJFK (In my opinion) aren't scary, let alone should make the list of the worlds scariest. The climbouts and turns to final might be a bit harrowing, but there is nothing about these runways that are scary..
Not when you have places like Courchevelle, France, Lukla (now Tenzing/Hillary.. VNLK), and Castlegar, British Columbia that send chills down the best pilot's backs.
