Note: All information from Boeing employees is confirmed via public sources or is explicitly stated by them to be public information before it is posted to this site.
Paul Fee is an electrical engineer who works for Boeing at Vandenberg AFB. He has provided a number of corrections to the schedule of upcoming west coast flights, and most recently sent along a very cool Delta II poster and some interesting promo cards for the Delta III and IV.
Gunter Krebs created Gunter's Space Page, an astoundingly extensive online database of all things space-related. He has provided several updates to the schedule as well as other developments.
Marc "Moose" Lavigne is an electrical checkout and telemetry engineer for the Delta program at Cape Canaveral. Lately, he has doubled as a "Voice of Delta," interpreting telemetry to provide real-time commentary of launch events during Boeing and NASA broadcasts. He has graciously provided corrections and additional information on several flights, including Deltas 179-184, 236, and 253. Moose also sent a copy of a McDonnell Douglas publication which logs all Thor stages built through 1972, a wealth of information which is yet to be incorporated on this site.
Justin Ray is chief reporter for Spaceflight Now, an online daily newsmagazine that has been rapidly expanding since its debut late in 1999. He often has the enviable task of attending launches to provide detailed online countdown journals. Justin was formerly a standout reporter for Florida Today Space Online, which was a good source for up-to-the-minute space news until it was absorbed by Space.com.
