"What is it in fact, this learning to fly? To be precise, it is 'to learn NOT to fly wrong.' To learn to become a pilot is to learn - not to let oneself fly too slowly. Not to let oneself turn without accelerating. Not to cross the controls. Not to do this, and not to do that. . . . To pilot is negation."

Cloud-flying requires practice, even if you have every modern instrument, and unless you keep calm and collected you will get into trouble after you have been inside a really thick one for a few minutes. In the very early days of aviation, 1912 to be correct, I emerged from a cloud upside down, much to my discomfort, as I didn't know how to get right way up again. I found out somehow, or I wouldn't be writing this.
