A Moscow-bound Delta flight had a scare this evening after a blown engine forced it to land back at JFK. Initial reports claimed that Delta Flight 30 had an engine fire, and some of the 193 people on board called 911 claiming to see flames or sparks. The plane circled around JFK dumping fuel; although the plane could fly with just one engine working, it was told to come back to the airport. Nobody was hurt, and now reports say that the blown engine may have been caused by a "bird strike," similar to what happened to U.S. Airways Flight 1549.
