The ruptured engine (#2) was shut down within a minute of the incident, in-flight. Two of the remaining engines (#3, #4) were shut down after landing. The last engine (#1) could not be shut down and had to be drowned in fire-fighting foam. This is in the article.

Engine 1 was continuing to operate after landing because the fuel shutoff valves were inoperative. Engine 2 was the engine that had the uncontained failure.
