The commercial spaceflight company launched a Falcon 9 rocket with a crewed Dragon on top. About 90 seconds into the flight, the Falcon 9’s engines switched off. Detecting that an anomaly had taken place, the Crewed Dragon fired its Draco rocket engines, separating it from the Falcon 9. As the Falcon 9 broke apart in midflight, the crewed Dragon soared away in safety. The spacecraft eventually splashed down in the Atlantic Ocean using parachutes. NASA and SpaceX will spend the next several months examining data garnered by the flight.
While the possibility of an inflight abort is an extreme event, it is not a theoretical one. In October 2018, a crewed Soyuz launch suffered an unplanned inflight abort. After the booster failed, the Soyuz capsule broke away and eventually landed near the launch site with its crewmembers, Russian cosmonaut Alexsey Ovchinin and American astronaut Nick Hague, shaken but alive and well.
