“Waldo” is a short story by Robert A. Heinlein originally published in “Astounding Science‐Fiction” August 1942, under the pseudonym Anson MacDonald.


North Power‐Air is in trouble. Their aircraft are crashing at an alarming rate, and no one can figure out the cause. Desperate for an answer, they turn to Waldo, a crippled genius who lives in a zero‐g home in orbit around Earth. But Waldo has little reason to want to help the rest of humanity—until he learns that the solution to Earth’s problems also hold the key to his own.
