STS-51F: Challenger aborts to orbit

ChallengerFor the first and only time in the history of the shuttle program, Space Shuttle Challenger does an in-flight abort maneuver – in this case, an Abort To Orbit (ATO) following the premature shutdown of one of the shuttle’s main engines. The potentially catastrophic shutdown of a second engine is narrowly avoided by a sharp-eyed ground controller, and Challenger makes it to orbit and the rest of the mission is conducted normally.
