Rocket mail

Rocket mail is the delivery of mail by rocket or missile. The rocket lands by deploying an internal parachute upon arrival. It has been attempted by various organizations in many countries, with varying levels of success. It has never become widely seen as being a viable option for delivering mail, due to the cost of the schemes and numerous failures. The collection of philatelic material ("stamps") used for (and depicting) rocket mail is part of a specialist branch of aerophilately known as astrophilately.
