    But i think it is possible because electric charges tend to accumulate on an aircraft during flight...i read this in book but dont know why this happens is it because of the frcition due to air?

    perhaps the firction between the plane and the air can cause a transfer of electrons onto or from the plane to the air. this is not transferred to you until you touch a conductor (you have carpets, rubber shoes and things insulating you) like a metal door knob.

    friction can lead to transfers of charge like static electricity when you rub a balloon on your hair - two insulators. perhaps this happens also with the air nad the paint on the plane (both electrical insulators)

    Im not that great at electricity but that seems like quite a convincing argument.

    If it relates to magnetic field of the Earth ... the aeroplane when moving in magnetic field will have a p.d across it due to Faraday's law, so when you touch it, there is a current through you. That's what I think
