The following are the start of some abstract notes on Black Arrow. Feel free to peruse.

• End 1963 - Harold Robinson and colleagues publish draft project study which described how Black Knight could be developed into an economical system capable of placing 90Kg into LEO.
• ........ - Saunders-Roc (a division of Westland Aircraft) in conjunction with Bristol Siddeley Engines contributed a detailed proposal of a 3 stage rocket. The 1st and 2nd stages would be enlarged versions of Black Knight powered by newer more powerful versions of the HTP-Kerosene Gamma Engine.
