The Astronauts Are Stranded at ISS - NASA Announces Boeing Starliner Incident as a Class A Accident

On February 19th, NASA announced the investigation results regarding a serious incident involving a crewed flight on Boeing’s Starliner spacecraft. The official report confirmed that this was classified as a “Class A” accident—the most severe safety standard according to NASA’s space safety criteria.

Control Loss Incident Causing Astronauts to Be Trapped

According to Jin10, the approach to the International Space Station (ISS) encountered a critical technical failure. The Starliner spacecraft completely lost control as it was aligning with the space station, resulting in significant financial consequences. This event left astronauts stranded at the ISS because the spacecraft was not functioning properly, turning the test flight into an emergency situation.

NASA Class A Accident Classification Standards

Under NASA’s independent classification system, an accident is designated as “Class A” if it meets one or more extremely strict criteria. These include: death or permanent disability of any individual; mission failure causing property damage exceeding $2 million; complete destruction of the crewed spacecraft; or situations where the spacecraft becomes uncontrollable under unforeseen circumstances.

The classification of Starliner as a Class A accident reflects the severity of the incident—not only in terms of economic damage but also the potential risks to astronaut lives and the safety of the entire program.
