As skywriting (in English as skywriting called) is a form of aerial advertising refers, in which a small plane , the sky Schreiber, one leaves from the ground visible message in the sky. To do this, the aircraft is controlled in a certain way, with a special smoke being emitted. The message can have various contents, for example advertising , but also private messages such as a congratulatory message or even a marriage proposal.
The smoke generator attached to the aircraft typically consists of a pressurized container that contains a low-viscosity oil (such as Chevron / Texaco "Canopus 13", formerly "Corvus Oil"). The oil is injected into a hot nozzle channel where it evaporates into a large amount of thick, white smoke. This method is also used in aerobatics to show the flown figures more impressively.
The result of sky writing is short-lived. The wind and the dissolution of the smoke cause it to disappear within a few minutes. In the meantime, however, methods have been developed that defy the wind for longer due to the writing technique (dot matrix method) and can therefore be seen for longer.
Major Jack C. Savage (1891–1945), an English pilot of the First World War , is regarded as the inventor of the sky writing . In 1922 he fitted an SE5a acquired from military stocks with two long exhaust pipes that merged under the tail unit . The oil was injected into the exhaust pipes. The plane is on display at the Science Museum in London today . JC Savage was also the inventor of the aircraft-mounted searchlights , the so-called Leigh lights , which were used with success in submarine hunting during World War II.
Until his death in July 2006, the last German sky writer was the Hamburg pilot Jörg Steber , who also carried out sightseeing flights with his DHC-2 Beaver seaplane in the port of Hamburg for many years .
