2001-Future

In the beginning of the 21st century, subsonic aviation focused on eliminating the pilot in favor of remotely operated or completely autonomous vehicles. Several Unmanned aerial vehicles or UAVs have been developed. In April 2001 the unmanned aircraft Global Hawk flew from Edwards AFB in the US to Australia non-stop and unrefuelled. This is the longest point-to-point flight ever undertaken by an unmanned aircraft, and took 23 hours and 23 minutes. In October 2003 the first totally autonomous flight across the Atlantic by a computer-controlled model aircraft occurred.

In commercial aviation, the early 21st century saw the end of an era with the retirement of Concorde. Supersonic flight was not very commercially viable, as the planes were required to fly over the oceans if they wanted to break the sound barrier. Concorde also was fuel hungry and could carry a limited amount of passengers due to its highly streamlined design. Nevertherless, it seems to have made a significant operating profit for British Airways.

Despite this setback, and the general slowing of progress, it is generally agreed that the 21st century will be a bright one for aviation. Planes and rockets offer unique capabilities in terms of speed and carrying capacity that should not be underestimated. As long as there is a need for people to get to places quickly, there will be a need for aviation.

The U.S. Centennial of Flight Commission was established in 1999 to encourage the broadest national and international participation in the celebration of 100 years of powered flight.[10] It publicized and encouraged a number of programs, projects and events intended to educate people about the history of aviation.
