“Don’t touch this… after it lands…” “When an airplane flies through the air… it builds up static electricity.” “Friction with air particles charges the entire aircraft…” “And when it lands… that charge needs to go somewhere.” “The landing gear touches the ground first…” “Releasing that built-up electricity instantly.” “Touch it too soon… and you could get shocked…” “That’s why ground crews wait… before approaching.”
