Blackburn Botha

First flight		28 December 1938
Introduced		12 December 1939
Retired		September 1944
Number built		580

The Blackburn B.26 Botha was a competitor to the Bristol, and entered service with the RAF in 1939. It was underpowered and was quickly withdrawn from operations.

In service, the Botha proved to be severely underpowered and unstable and there were a number of fatal crashes in 1940. Both airframe and engine were subject to further development work, but it was decided to withdraw the type from front-line service. At this point, the Air Staff made the ill-advised decision to transfer the surviving aircraft to training units, which inevitably resulted in further casualties.

The type was finally retired in September 1944. In total, 580 aircraft were built.

The Bird of Prey aircraft was developed intending to demonstrate stealth technology . it was a low cost program ( a price of $67 million) compared to many other programs . It developed technology and materials which would later be used on Boeing's X-45 unmanned combat air vehicle. It is characterized as a technology demonstrator.Development of the Bird of Prey began in 1992 by McDonnell Douglas's Phantom Works division for special projects. The first flight was in 1996, and 39 more were performed through the program's conclusion in 1999.The Bird of Prey is designed to prevent shadows and is believed to have been used to test active camouflage , which would involve its surfaces changing color or luminosity to match the surroundings.
