Letter: Briefly

"The correct way to greet a Martian" was defined by Jet Morgan in the classic 1950s radio series Journey Into Space (13 July). When Jet's spaceship first made contact with an alien species the crew was overwhelmed by their grotesque ugliness. In one of the great empathic statements of all time Jet explained to his crew that the aliens saw humans as being no less grotesque. So the golden rule when greeting a Martian is: refrain from vomiting.
