On May 5, 2019, an Aeroflot airliner crashed at Moscow's Sheremetyevo airport, killing 41 of the 73 passengers. The plane, a Sukhoi Superjet-100, was bound for the northern city of Murmansk, but turned around after reportedly being struck lightning and losing their autopilot and radio-communications channel. Back in Moscow the aircraft landed hard and burst into flames, and more than half the passengers lost their lives. The causes of the crash are still under investigation, and in addition to the lightning strike, authorities have stated that a pilot error or technical malfunction may have occurred.
