NH2Z. That's his radio call sign, but he's also known as Al Shaver, a retired United Airlines senior captain who flew 747s on weekly international routes. In his days off, he attended the University of Chicago where he met his wife Ann (WH2E) and where each earned doctoral degrees in social sciences. Now living in Hawaii, they learned of SATERN through a notice about a Salvation Army disaster services seminar. SATERN so intrigued them that they flew to the mainland to attend. Today they are SATERN volunteers and edit its newsletter, The SATERN Ring.
