As designed, the flight computer then recomputed a new ascent profile in real time to ensure Dragon’s entry into orbit for subsequent rendezvous and berthing with the ISS. This was achieved, and there was no effect on Dragon or the cargo resupply mission.
Falcon 9 did exactly what it was designed to do. Like the Saturn V, which experienced engine loss on two flights, Falcon 9 is designed to handle an engine out situation and still complete its mission. .
However - is this the best thing ever? Because it occurred we actually know of its ability to handle emergencies with its safety system responses. That the ship so smoothly handled the difficulty that an onlooked had to be told it occurred is remarkable!
The Falcon 9 bears the number 9 not by mistake, it has nine engines and was designed to fly to space if one of them were to fail.
Good job SpaceX!
