An aircraft fuselage becomes positively charged due to friction with dust and ice particles in the atmosphere during flight. After landing, before refueling can begin, a ground technician connects a conducting copper cable from the metal fuselage to the earth.
Explain, in terms of electron movement, how this process discharges the aircraft.
