2017 Love Skywriting Forever Postage Stamps Sheet First-Class

Skywriting has been amazing people with its beauty and mystery since the early 1900s.  It was first used by British Royal Air Force pilots to send messages to the ground when other communications failed.  It then became an advertising tool for companies like Pepsi.  In more recent years, people have hired skywriters to write personal messages to loved ones.

There are two types of skywriting: traditional and skytyping.  Both forms feed paraffin oil through the plane’s exhaust to create a trail of white smoke.  In traditional skywriting, the release of oil is controlled by a switch in the plane’s cockpit.  For skytyping, a computer controls when the smoke is released.
