GENERAL The Canadian-built robotic arm, Canadarm2, on the International Space Station weighs almost 2 tons. Why does it need to be so strong and heavy when the items that it moves are weightless in orbit? Why is it a good idea to have available a very small quantity of water when draining fuel during preflight inspections? From reader Bob Lippincott: After France fell to Germany in 1940, the Royal Canadian Air Force received North American NA-64 Yale trainers (T-6s with fixed landing gear) originally destined for the French Air Force.
