My one gear warning save happened while doing touch and goes with my Mooney.
Neglected to raise the gear on take-off, then abeam the numbers, flipped the
gear switch up. Briefly wondered why that darn distracting beep-beep-beep
thing was making such a racket. Within a second or two, came to my senses
and exclaiming to myself, "Holy Bananas" (or some similar, equally
appropriate thing). Switch down, no damage, glad there's a gear warning horn
even though I'm originally a Brit'.
