Whew, I thought it was just me. Absolutely no problem in an aircraft, but try and get me to clean the gutters.
The airport at HSP (Hot Springs VA) is on top of a butte, they just graded the top off the mountain and laid the asphalt, as it were. The drop offs on either end must be nearly a thousand feet down to the valley floor. On departure out of there once, just as we flew over the end of the runway, I glanced outside. The sensation was hard to describe, but it was like losing all vertical reference. I could relate to the aircraft climbing, but not the ground falling away. I gave control to the FO, and it took me several minutes before I felt well enough to resume flying. Has anyone ever experienced anything like this before?
