Gosh, I'm so excited, I could....
Today I spoke to Ian Whittle, the son of Sir Frank. Now Sir Frank and F. G. were working together on the M.52 supersonic design weren't they! It was to be powered by the 200 lb Whittle W.2/700 jet engine with augmentor (reheat).
Since it was a business call and on his ticket, I invited Ian to browse the thread.
What a day this has been!
