| To E.{Mr Elliott - Chief Engineer} X1729 Hs{Lord Ernest Hives - Chair}/Rm.{William Robotham - Chief Engineer}2/KW.13.9.34. Here is some more information relative to ground clearances. My own opinion is that we shall have to go up at least 1 1/2" on all the central portions of the SpectreCodename for Phantom III for English conditions, and probably more for Colonial.
