On April 17, 1970, Apollo 13 returned to Earth after suffering a severe malfunction in space.
The mission had launched six days earlier in the hopes of sending three astronauts to the moon. Two days into the mission, an oxygen tank blew up in the spacecraft, endangering the lives of James A. Lovell, John L. Swigert and Fred W. Haise.
The plan to land on the moon was aborted, and the new focus became getting the three men back to Earth safely.
On this date, 44 years ago, Apollo 13 safely splashed down in the Pacific Ocean.
