D-Day Stripes, or invasion stripes were alternating black and white bands painted on the fuselages and wings of Allied World War II aircraft, for the purpose of increased recognition by friendly forces (and thus reduced friendly fire incidents) during and after the Normandy Landings. The bands, consisting of three white and two black bands, wrapped around the rear of an aircraft fuselage just in front of the empennage (tail) and from front to back around both the upper and lower surfaces of the wings.
