Why are all air­lin­ers white?

Science Illustrated - - ASK US -

As pas­sen­gers leave a large plane in the air­port, it is of­ten a chal­lenge to keep the air­craft cool. A white plane body re­flects more so­lar ra­di­a­tion, keep­ing the tem­per­a­ture down. The white colour also pro­tects the air­craft against UV light, which is more pow­er­ful at high al­ti­tudes.
