Boeing argued this week that a final report into the disappearance of Malaysia Air Flight 370 supports its bid to dismiss dozens of lawsuits brought in U.S. courts on behalf of the families of deceased passengers.

The report, released on Monday by a Malaysia-based international group of government investigators, failed to identify exactly what happened to the doomed Boeing 777, which disappeared over the Indian Ocean in 2014 along with 239 passengers and crew members. But on Wednesday, Boeing filed a notice in court referencing the 495-page report, which pointed to “the possibility of intervention by a third party” and found no evidence of “a mechanical malfunction with the aircraft’s airframe, control systems, fuel or engines.”
