Going into Thursday's mission, the current version of SpaceX's Falcon 9 rocket, known as the Falcon 9 Block 5, was indisputably the most reliable launch vehicle in history. Since debuting in May 2018, the Falcon 9 Block 5, which NASA has certified for astronaut flights, never had a mission failure in all of its 297 launches before the ill-fated Starlink 9-3 mission.
Assuming the Starlink satellites can't be saved, and if Thursday night's launch is scored a complete mission failure, the Falcon 9 Block 5 still has a 99.7 percent success rate. This is still an enviable number for any launch company.
99.7% success rate is still pretty damn impressive.
