When NASA launched the Commercial Crew programdid so with a clear idea: to partner with private companies that would design and operate their own ships under fixed-price contracts. Boeing and SpaceX have been part of this scheme since its origin, with the aim of guaranteeing regular manned access to low orbit. The Starliner manned test flight in June 2024 was to complete the technical validation process of the Boeing capsule before its certification, but anomalies detected during the mission completely altered the initial plan. Now, when officially classifying This test as a “Type A Incident”, NASA places what happened at the highest level of its incident scale and recognizes that the magnitude of the episode goes beyond a simple technical setback.
What happened in 2024. On June 5, 2024, the CST-100 Starliner took off heading to the International Space Station on its first crewed flight with NASA astronauts Butch Wilmore and Suni Williams on board. The mission was initially planned to last between eight and fourteen days as a comprehensive test of the system. However, during the approach They detected helium leaks and failures in the thrustersand NASA explained that a loss of maneuverability occurred as the crew approached the station, although control was regained before docking. The stay ended up extending up to 93 days and, after reviewing the flight data and performing tests on the ground, The space agency decided that the vehicle would return in September 2024 without the astronautswhich finally returned to Earth in March 2025 aboard SpaceX’s Crew-9 mission.
A devastating report. The independent investigation team, formed in February 2025, examined the technical, organizational and cultural factors that contributed to the problems with the test flight. According to their conclusions, there was a combination of hardware failures, gaps in the qualification processes, leadership errors and cultural dysfunctions that generated risk conditions incompatible with the safety standards of the agency’s manned flight program. NASA has indicated that it accepts this document as the final report and that work to identify the technical root cause continues.
What does “Type A mishap” (Type A Incident) mean? NASA uses this category as the highest level within its incident system. Let us remember that this definition includes cases such as damages exceeding 2 million dollars, the loss of control or destruction of a vehicle or the loss of human life. In the case of the Starliner flight, there were no injuries and, according to the agency, the mission regained control before docking, but there was a loss of maneuverability during the approach and associated financial damages. The designation recognizes that there was potential for a major mishap and that the conditions generated cannot be dismissed as a simple technical mismatch.

NASA Administrator Jared Isaacman was explicit in addressing the cultural dimension of the problem. “It is decision-making and leadership that, if left unchecked, could create a culture incompatible with human spaceflight,” he declared at the press conference. The head of the agency maintained that the classification as “Type A mishap” seeks to “make things clear” and ensure that what happened is recorded appropriately for future learning. He also admitted that allowing the program itself to initially investigate itself was “incompatible with NASA’s safety culture,” a practice that, he explained, it has decided to correct.
Boeing’s response. In a statement released after the report’s publicationthe company stated that it remains “committed to NASA’s vision of having two commercial crew providers” and thanked the agency for the research. Boeing maintains that in the 18 months since the test flight it has made progress in corrective actions to address the technical challenges detected and has driven cultural changes within the team.
