"Federal Aviation Administration (FAA) data show that 50 commercial space launches from 2000 through mid-January 2023 resulted in “mishaps”—the industry term for incidents such as catastrophic explosions and other failures. This represents about 12 percent of 433 launches during the period and caused no fatalities, serious injuries, or significant property damage to the public."

and

"When mishaps occur, FAA can conduct an investigation itself or instead authorize launch operators to lead investigations of their own mishaps under FAA oversight, according to FAA. In practice, however, FAA has authorized operator-led investigations for all mishaps where it had lead investigative authority, GAO found."
