From Stuart Arnold
I was interested to read that 1994 was the 30th anniversary of Ed White’s space walk from Gemini 4 (“1995 and all that,” 24/31 December). Maybe the author should also have remembered the Russian cosmonaut Leonov, who performed a space walk from Voskhod 2. He achieved this feat some time before White, this making it the first space walk ever to be peformed.
