On the dangers of flight

Found these quotes recently:

In the catalog of human endeavors, few activities are as fragile as flight. The air offers no mercy for mistakes and no second chances. Flight is, as Winston Churchill observed, “an extremely dangerous, jealous and exacting mistress, ” demanding unfettered attention and respect.
WINSTON S. CHURCHILL, THOUGHTS AND ADVENTURES 128 (Leo Cooper pub., 1990).

“Flying is not inherently dangerous but very intolerant of errors.” (Which appears to be a twist on: “Aviation in itself is not inherently dangerous. But to an even greater degree than the sea, it is terribly unforgiving of any carelessness, incapacity or neglect.” Captain A. G. Lamplugh, British Aviation Insurance Group, London.)
