My friend admitted to me that although he had never before told anyone
on the ground, he, too, had experienced the same frightening phenomenon.
Feet securely in place on the robotic arm, he was being conveyed to
the far end of the telescope, well out of the confines of the payload bay.
So far, so good, he said. But in order to begin his repair work, he had
to extricate himself from the stabilizing footloops and cross over
to the telescope. Feet now free and reaching across the two-foot gap to the
end of the telescope, he unexpectedly and overwhelmingly felt the
sensation of falling off the edge of the world!
