That explains the giant TFR around Castle I saw this morning..

President Obama used a speech at Yosemite National Park today to tout his conservation legacy while calling for more action to prevent climate change, which he has said is the greatest threat facing future generations. On a side note; Air Force One cost $$228,288 an hour to fly.

A little known fact;
United Airlines is the only commercial airline to have operated Executive One, the call sign given to a civilian flight on which the U.S. President is aboard. On 26 December 1973, to "set an example for the rest of the nation during the current energy crisis" and to "demonstrate his confidence in the airlines", then-President Richard Nixon became the only sitting president to travel on a regularly scheduled commercial airline flight when he flew on a United Airlines DC-10 from Washington Dulles International Airport to Los Angeles International Airport. A Nixon aide carried a suitcase-sized secure communication device on board the plane, so that the President could remain in contact with Washington in the event of an emergency.
