| X1166 E/Ltd. c. Hs{Lord Ernest Hives - Chair}/Gry.{Shadwell Grylls} E.3/HP.5.5.36. re Hydraulic Jacks on Phantom III. In connection with the controls for the above, a small point, but one worth altering, I consider, is that the arrows indicating the direction of rotation are not sufficiently clear, the heads and the tails appearing too much alike when the handles are dirty and viewed in a poor light. Will you please arrange for these to be more clearly marked by increasing the size of the arrow head. E.{Mr Elliott - Chief Engineer} | ||
