E.{Mr Elliott - Chief Engineer} Hs.{Lord Ernest Hives - Chair} By 43589 Rg{Mr Rowledge}5/LW.28. 5. 27 The following paragraphs occur in a report by Lp.{Mr Lappin} of a conversation with Mr. Flohr, Chief Engineer of the Luft Hansa, who are running a number of our Eagle IX's and Commercial Service:- "Flohr expressed himself as being entirely satisfied with the Eagle IX engine, but regretted that it was not a little more powerful and it seems certain that no further engines of this type will be ordered." "It is interesting to know in regard to Eagle IX's that the valve seat erosion trouble which they have previously experienced has now entirely disappeared and they are unable to offer any explanation for same."
