Technology isn't lost in space

``Space Development,'' July 20, brought back exciting memories, and also sadness. In 1970 I attended a lecture regarding development of resources in space. I've forgotten the predicted date for a working space station, but it was supposed to be before 1990. It's sad that we can't foresee the benefits of space technology; it seems that, especially now, we need a clear vision. Pat Barrett, Foster City, Calif.
