right on the edge for height to bother me. Being in a tall building does not bother me OTHER THAN worrying about what to do in case of a fire.
On my backpacking trips I was on top of many cliffs... including the King of them all... Half Dome in Yosemite. But ALWAYS, no exceptions, I went to the edge crawling on my stomach... NEVER upright. it was incredible to me how many people will walk right up to the edge, even with toes over the edge. A few cliffs I wouldn't approach the edge at all because it was on a downslope... granite is slippery.
Planes, even small planes, don't bother me in the least. It pretty much has to be a cliff for height to bother me... but cliffs bother me enough that I will not stand on the edge of one.
