LAN mechanic applying speed tape on an Airbus A320

LAN mechanic applying speed tape on the left engine nacelle of an Airbus A320. Briefly, speed tape is an aluminized tape used to do minor repairs on aircraft. It is used as a temporary repair material until a more permanent repair can be carried out. It has an appearance similar to duct tape, for which it is sometimes mistaken, but its adhesive is capable of sticking on an airplane fuselage or wing at high speeds, hence the name.
