tan‧gi‧ble, adj. /ˈtændʒəbəl/
During the NASA Mercury, Gemini, and Apollo missions, it was important for the engineers and the astronauts to know which spacecraft components could be ruined mid-flight. To aid in this, both groups were provided with lists of components divided by whether the component would cease to function if the ship’s complement of Tang® were spilled on it. The navigational computer and oxygen circulator were thus considered tangible components. The astronauts’ bravery was intangible – unless, of course, the Tang® had turned.
