Q.What is safer to be in when lightening strikes an aeroplane or car?
A.Aeroplanes and cars both act as Faraday cages, protecting the occupants, but lightning has (very occasionally) caused plane crashes, so a car is safer.
Q.Is it safer to have your house windows opem or closed during a lightening storm
A.There is no need to close the windows during a thunderstorm - lightning can pass through windows, so there's no point. Strikes inside houses are rare.
Q.Do planes often get struck by lightening
A.Aeroplanes are not earthed & are, on average, struck by lightning twice per year. However, the metal casing protects the passengers from the electricity.
Q.Why would lightening strike an aeroplane?
A.Lightening would strike an aeroplane because they are made of metal (an excellent conductor), and fly at 33,000ft, through clouds.
