They do...actually lightening often strikes aircraft...usually with little or no effect as it the voltage is discharged along the metalic structure and carries on it's journey..all in a millisecond.
Newer aircraft made from composite marterial ie: Kevlar, epoxies, carbon-graphite etc have a more difficult time dealing with lightening as thier structures are not as conductive and the resistance that's incurred can lead to structual damage if precautions aren't taken. Such precautions include conductive strips running along the fusalage as well as conductive wicks to provide a discharge path for the energy. Still the discharge can cause hidden damage that's difficult to detect..damage at a molecular level.(Sikorsky S76 that went down off the coast of Scotland.....rotor blades damaged by lightening 4yrs prior...composite construction)
Hope this helps

actually the aircraft are strike by the lightning.The lightning strike usually carrying a current,so they can give an effect to the aircraft body and instrument.To avoid it, an aircraft have a system to discharge the current on the lightning strike that flow on the aircraft.e.g static wick.Static wick are fabricated with a wick of wire or a conductive element on one end, which provides a continuous low resistance discharge path between the aircraft and the air.It will illuminates the current from the lightning strike from the aircraft.

The reason you don't hear about planes getting shot out of the sky by lightning is the same reason a person in a car is perfectly safe from lightning: The current travels to the ground along the path of least resistance, which is always along the outer edge of the metallic framework. The current never goes inside, as the charge from the electrons repels each other..

because lightning strike "aeroplane"

Aircraft actually do get hit by lighting probably more then people think.

'cause lightening moves too fast for the plane to line up on and intentionally hit it!

the lighting often strikes planes but they are made to not crash!!!

because it doesn't want lightening to strike back.
