Just watched an excellent interview with Dan Sherman at richplanet.com The interview is a few months old and Dan's story is not new, but it is very in depth with good questions.
I read Project Preserve Destiny many years ago and have listened to several interviews with Dan since then. His testimony has remained extemely consistant over the years despite potential for exageration and this fact adds a great deal to his credibility.
His account of working as an "intuitive Communitator" for the NSA in parallel to his official role as a USAF SIGINT specialist is fascinating if you aren't already familiar with it and well worth revisiting if you are.
