Actually, “Failure is not an option” is a Gene Kranz book. Not C. Kraft.

Something similar was considered, though not actually done, when NASA's first
attempt launch a Mercury capsule resulted in a four-inch flight in November
1961. From Wikipedia (en.wikipedia.org/wiki/Mercury-Redstone_1):
"[T]he fully fueled and powered-up Redstone was now sitting on LC-5 with
nothing securing it to the pad. Various other dangers existed as well such as
the capsule's retrorocket package and the range safety
<https://en.wikipedia.org/wiki/Range_safety> destruct charges. Furthermore,
the capsule's main and reserve parachutes were hanging down the side of the
rocket, threatening to tip it over if they caught enough wind. Fortunately, the
weather conditions were favorable. Amid the panicked atmosphere in the control
room, the launch team was unable to come up with quick and viable options to
rectify the situation. Chris Kraft, the now-frustrated flight director,
rejected several unsafe interventions, including getting a rifle and shooting
holes in the booster's propellant tanks to depressurize them. He eventually
took the advice of one of the test engineers to simply wait out the battery
discharge and let the oxidizer boil off."
Wikipedia cite's Kraft's biography, _Failure is not an Option_, as its source.

I've heard similar anecdotes - has this technique ever actually been used?
