The rain was coming down pretty hard but what got my attention was at least one lightning flash that was not too far from the plane. Are most commercial airliners protected against lightning flashes? Has there ever been a record of lightning striking an airliner and if so, what were the consequences? ---- While commercial airliners do not get hit often by lightning, it is not uncommon. Airliners have static discharge wicks, which look like black "antennas" sticking out the trailing edge of wings and tail surfaces. Lightning tends to hit these rather than the fuselage. These static wicks do another duty by dissapating static charge which accumulates on the fuselage into the air stream by a mechanism I don't know too much about, quite frankly. The main problem with static buildup is that it can affect the comm radios and other RF devices. Airlines go through much effort to insure that static wicks and antennas are securely bonded to the airframe.
