The space age is more than a half century old. The age of aviation is much older still. In both cases, the heritage is one of all mankind. In both cases, intangible and tangible heritage are found in many countries, In the case of heritage sites, they are located not only in many countries but also on the moon, on Mars, and in outer space. It is time that there be a global effort for the protection of this heritage.

I would suggest that UNESCO begin to consider aerospace cultural heritage using its convening power to hold meetings of experts from around the world to exchange ideas and concepts. It could serve as a clearinghouse for such ideas. Eventually, if its member states felt the need, it might provide some legal instruments relating to aerospace heritage, such as recommendations for their preservation and protection, or even conventions for the protection of extraterrestrial heritage.
