On Monday, NASA’s Independent Review Team (IRT) published the first public report on the SpaceX CRS-7 failure. The accident occurred on June 28th, 2015 when a Falcon 9 rocket’s second stage experienced an over-pressurization event during first stage ascent. The incident led to a launch vehicle failure approximately two minutes and nineteen seconds into flight. SpaceX blamed the accident on a manufacturing defect involving a steel strut. However, the IRT report blames a design error on SpaceX’s behalf.
