Aeroflot Flight SU1492 burst into flames while making an emergency landing at Sheremetyevo International Airport in Moscow on Sunday. Of the 78 passengers and crew on board the Russian-made Sukhoi SuperJet 100, 41 perished in the fire.

The jet's flight data and cockpit voice recorders have been recovered from the wreckage. An investigation led by Russia's Transport Minister is underway.

The exact cause of the fire that engulfed airliner has not been revealed.

One of the jet's pilots, Denis Yevdokimov, told Russian media that the emergency landing was triggered by a malfunction in the plane's communications system brought on by lightning, AFP reported. However, the pilot didn't clarify if the aircraft was actually struck by lightning.

If the jet was indeed struck by lightning, it's unclear how much damage was done beyond the communications system. Video of the emergency landing does not appear to show any smoke or flames until the jet reaches the airport, bouncing violently down the runway.

Regardless, Flight SU1492 has brought the threat of lightning strikes to the forefront of the traveling public's consciousness.

"This is not something you hear very often, if ever," Teal Group aviation analyst Richard Aboulafia said regarding the pilot's report that lightning caused a malfunction.

Lightning strikes on aircraft are a daily occurrence around the world.

According to Aboulafia, when lightning strikes an airliner, the electricity passes through the plane's aluminum outer skin. In the process, the fuselage acts as a Faraday cage, protecting the occupants from the jolt of electricity. In addition, the internal electronics on modern commercial aircraft are also designed to withstand the electric surge of a lightning strike.

The most memorable incident of a commercial airliner being brought down by lightning occurred on December 8, 1963, when a lightning strike ignited the fuel tank in the leftwing of PanAm Flight 214. The resulting explosion caused a portion of the wing to break off midflight. The crash killed all 81 passengers and crew on board the Boeing 707. PanAm 214 is also the last crash of an airliner in the US where lightning was cited as a direct cause.
