What looks like it needs a wash is in fact a film. Since 14 October 2023, SWISS has been the first airline in the world to use the innovative Aeroshark technology in its aircraft. The transparent Aeroshark film consists of millions of "riblets", small protrusions just 50 micrometres high, which replicate the highly hydrodynamic skin of sharks and thus reduce the air resistance of an aircraft wherever it has been applied (aircraft fuselage and engine nacelles), thereby reducing fuel consumption and carbon dioxide emissions.
