What is Cana-arm?
1.
Also known as the "Canadarm" and "Canadian Arm." The robotic crane on the back of the US'an space shuttle and the international space station. Seems as if the space shuttle isn't anything except a flying tin can without the Cana-Arm...
Johnny Canuck isn't too enthused about the Cana-Arm: it may be the only part of the space shuttle that always works, but it's just another part of the US'an military-industrial complex.
