Airmail (or air mail, in French Par avion) is mail that is transported by aircraft. It typically arrives more quickly than surface mail, and usually costs more to send. Airmail may be the only option for sending mail to some destinations, such as overseas, if the mail cannot wait the time it would take to arrive by ship, sometimes weeks. Specific instances of a letter being delivered by air long predate the introduction of Airmail as a regularly scheduled service available to the general public. Although homing pigeons had long been used to send messages (an activity known as pigeon mail), the first mail to be carried by an air vehicle was on January 7, 1785, on a balloon flight from Dover to France near Calais. During the first aerial flight in North America by balloon on January 9, 1793, from Philadelphia to Deptford, New Jersey, Jean-Pierre Blanchard carried a personal letter from George Washington to be delivered to the owner of whatever property Blanchard happened to land on, making the flight the first delivery of air mail in the United States. The first official air mail delivery in the United States took place on August 17, 1859, when John Wise piloted a balloon starting in Lafayette, Indiana with a destination of New York. Weather issues forced him to land in Crawfordsville, Indiana and the mail reached its final destination via train. In 1959 the U.S. Postal Service issued a 7 cent stamp commemorating the event.
