Air France Flight 447

Air France and aircraft maker Airbus go on trial in Paris today on charges of involuntary manslaughter in the 2009 crash of a flight from Brazil, killing all 228 people aboard.

The case focuses on alleged insufficient pilot training and a defective speed monitoring probe, which was quickly replaced on planes worldwide in the months after the accident.

Warning alarms in AirAsia flight QZ8501 were "screaming" as the pilots desperately tried to stabilise the plane just before it plunged into the Java Sea last month, a crash investigator said Jan. 21.
