FROM WIKIPEDIA COMMONS
Continental Air Defense Command (CONAD) was a Unified Combatant Command of the United States Department of Defense, tasked with air defense for the Continental United States. It comprised Army, Air Force, and Navy components. It included Army Project Nikemissiles (Ajax and Hercules) anti-aircraft defenses and USAF interceptors (manned aircraft and BOMARC missiles). The primary purpose of continental air defense during the CONAD period was to provide sufficient attack warning of a Soviet bomber air raid to ensure Strategic Air Command could launch a counterattack without being destroyed. CONAD controlled nuclear air defense weapons such as the 10 kiloton W-40 nuclear warhead on the CIM-10B BOMARC. The command was disestablished in 1975, and Aerospace Defense Command became the major U.S. component of North American Air Defense Command (NORAD).
NORAD Tracks Santa is an annual Christmas-themed program in which North American Aerospace Defense Command (NORAD) simulates the tracking of Santa Claus, who is said to leave the North Pole to travel around the world on his mission to deliver presents to children every year on Christmas Eve. The program starts on December 1, but the actual Santa-tracking simulation starts at midnight annually on December 23. It is a community outreach function of NORAD, and has been held annually since 1955.
Although NORAD claims to use radar and other technologies to track Santa, the website merely simulates the tracking of Santa and displays predetermined location information to users.
The program follows the tradition of the September 1897 editorial “Yes, Virginia, there is a Santa Claus” in the New York Sun.
Question of the Day

Home Hint of the Day
Use one-gallon metal paint-thinner cans for storing hardware and other small objects in your workshop. Cut the top off each can with a can opener and pour out any remaining thinner. There’s no need to wash the cans; the last traces of the thinner will evaporate.
Word of the Day
A summer’s-day palindrome: It’s “too hot to hoot.”
