1. An aircraft comprising: a flying wing having a longitudinal, horizontal and vertical axis, said flying wing further having a first leading edge portion having a first sweep angle and a second leading edge portion having a second sweep angle equivalent to or less than said first sweep angle; anda canard mounted on said first leading edge portion;wherein said canard includes a fixed leading edge and a fixed trailing edge;wherein said canard is retractable within the vehicle;a pressurized air distribution system for providing pressurized air over said canard; andsaid pressurized air distribution system including a control valve for controlling the flow of air over the canard to provide pitch control of the aircraft. 2. The aircraft as set forth in claim 1 comprising: said first sweep angle is between 30 and 80 degrees; andsaid second sweep angle is between 0 and 80 degrees. 3. The aircraft as set forth in claim 2 wherein the aircraft has an overall length, the aircraft comprising said first portion extending back from the nose end between 40 and 60 percent of the overall length of the aircraft. 4. The aircraft as set forth in claim 3 wherein the aircraft includes a tail end comprising: the trailing edge of said flying wing extending over a third portion of the length of aircraft at a sweep angle of 0 to 45 degrees; anda fourth portion extending rearward at a sweep angle between 0 degrees and that parallel to the second sweep angle. 5. The aircraft as set forth in claim 4 comprising: a plurality of extendable flaps mounted on said trailing edge. 6. The aircraft as set forth in claim 1 wherein said pressurized air distribution system includes: a first air distribution system mounted on said canard for distributing pressurized air there over;a second air distribution system mounted on said flying wing for distributing pressurized air over said flaps;a propulsion system having at least one jet engine, said propulsion system adapted to provide pressurized air; andmeans for conducting pressurized air coupled with said at least one jet engine;said means for conducting pressurized air being also coupled said first and second air distribution systems. 7. The aircraft as set forth in claim 6 wherein the control valve is mounted in said means for controlling airflow to said first air distribution system, such that airflow over said canard can be varied to adjust the lift produced by said canard to provide pitch control. 8. The aircraft as recited in claim 1 including first and second retractable canards mounted on the aircraft leading edge portion on opposing sides of the aircraft longitudinal axis; wherein the pressurized air distribution system provides pressurized air over each of said first and second canards; and first and second control valves for controlling the flow of air over the canards, the first and second controlled valves being operative to control the flow air over the first and second canards, respectively. 9. An aircraft comprising: a flying wing having a longitudinal, horizontal and vertical axis, said flying wing further having a first leading edge portion having a first sweep angle and a second leading edge portion having a second sweep angle less than or equal to said first sweep angle;a plurality of trailing edge flaps mounted on said flying wing;a retractable canard mounted near the nose of said flying wing;a pressurized air distribution system mounted in said flying wing for providing pressurized air over said second canard and said flaps; andsaid pressurized air distribution system including a control valve for controlling the flow of air over said canard to provide pitch control of the aircraft;wherein the canard includes a fixed leading edge and a fixed trailing edge. 10. The aircraft as set forth in claim 9 wherein the canard is at an angle to the horizontal axis of between plus or minus 20 degrees. 11. The aircraft as set forth in claim 10 wherein said pressurized air distribution system includes: a first air distribution system mounted on said canard for distributing air there over;a second air distribution system mounted on said flying wing for distributing air over said flaps;a propulsive system having at least one propulsion system, said propulsion system adapted to provide pressurized air; andmeans for conducting pressurized air coupled to said at least one propulsion system;said means for conducting pressurized air being also coupled to said first and second air distribution systems. 12. The aircraft as set forth in claim 11 wherein the control valve is mounted in said means for controlling airflow to said first distribution system, such that airflow over said canard can be varied to adjust the lift produced by said canard to provide pitch control. 13. The aircraft as recited in claim 9 including first and second retractable canards mounted on the aircraft leading edge portion on opposing sides of the aircraft longitudinal axis; wherein the pressurized air distribution system provides pressurized air over each of said first and second canards; and first and second control valves for controlling the flow of air over the canards, the first and second controlled valves being operative to control the flow air over the first and second canards, respectively.
