| To EJJ. X1209 Hs{Lord Ernest Hives - Chair}/Rm.{William Robotham - Chief Engineer}12/KW.5.9.35. SpectreCodename for Phantom III Test Bed. We are having a certain amount of trouble with the Heenan & Froude brake on the SpectreCodename for Phantom III test bed. We understand that there is no spare brake of this type in the factory. It is clearly impossible for us to hold up the SpectreCodename for Phantom III work while the brake is repaired, furthermore there will be a demand for a spare brake by the Production test bed. We recommend that you obtain a spare brake. Hs{Lord Ernest Hives - Chair}/Rm.{William Robotham - Chief Engineer} | ||
