. One of the men who designed the engine was C. Donald.

The first two vehicles were 'proving rounds' - that is, launches without a payload in order to prove the design of the rocket. The third firing carried a re-entry vehicle. This flight showed that the chosen design for the re-entry body was a success.

Further firings with different heads showed up some unusual phenomena, and further tests under the code names Gaslight and Dazzle were carried out in conjunction with the United States.

A variety of heads were flown in these tests, including a plain copper sphere and a silica sphere. Heads composed of a composite asbestos

-based material known as Durestos were also flown, and later tests finalised on a cone-shaped head re-entering pointed-end first, as used on many subsequent missile RVs.

All the re-entry firings took place on clear moonless nights, so that the luminous wake of the re-entry body could be observed photographically.

An improved Black Knight, with the tank diameter increased from 36 inches to 54 inches, and a more powerful second stage, named Kestrel, was proposed for a further set of experiments codenamed 'Crusade'.
