Daily Mail: Has Lockheed Martin FINISHED building the secret hypersonic successor to the Blackbird? Skunkworks boss hints SR-72 bomber has 'already been made' Jack O'Banion of Lockheed Martin, let slip at a conference the aircraft has already been made. The SR-72 hypersonic plane will be a strike and reconnaissance aircraft that tops Mach 6.  The SR-71 had a speed of Mach 3. This aircraft is said to be twice as fast and can carry bombs.  It appears to be very stealthy in its design.  The speed is the result of finally mastering hypersonic engines.

Daily Mail: Is THIS the America's newest top-secret spy plane? Clearest picture yet of mystery aircraft spotted flying over Kansas just weeks after being seen in Texas A new image shows a mysterious aircraft flying over Kansas (main). The jet appears to be the same one that was spotted over Texas last month. Photographer Jeff Templin says it may have been as high as passenger jets. A retired Marine previously said the mysterious plane is the SR-72 (inset), which is designed to cross entire continents in less than an hour. There is much more at the link above.  I am still leaning toward a much smaller stealth drone that is also mentioned in the article.  I am not sure they have perfected the engines needed for the kind of speed it would take to get across the country in less than an hour.
