On this day in 1970, an oxygen tank exploded on Apollo 13, which
prevented the planned moon landing.

The repair dubbed the "mail box" that saved the Apollo 13 astronauts. After an oxygen tank exploded, the three men
had to retreat to the Lunar Module and use duct tape, along
with plastic plastic bags and lithium hydroxide canisters to
build a makeshift CO2 scrubber.
