Henry has written an incredibly superfluous sentence in his column whn, in short, he should have explained, ""As long as he lived, he loved her.""

The space agency sends the UFO an urgent message littered with gobbledygook, promting the UFO's plain response, ""Doesn't anyone [on Earth] speak English?"" Morton, Henry, and Miss Newton tell the space agency to send the message, ""Turn back before you destroy the Earth,"" which the UFO understands perfectly, and complies.
