Spit/109 sea level speed comparisons in 1.08 beta patch

[Crumpp]

classified documents from Vickers-Supermarine

It is the ones from Mtt that the RAE did not have access too. Germany was at war with England at the time so they were not exactly sharing information.

Instead, a pilot with little experience with a selectable pitch propeller had to go up and operate it to record data using a very difficult method of gathering airspeed data.

My Spitfire analysis is in agreement with the RAE's analysis.

The relative performance is not in agreement, but that has to do with Bf-109 performance and not the Spitfire's.

It's great that some of the information survived all these years, I've often wondered. Here in the States much of our early mechanical history, can be found in the library of Congress.

You can find all the patent information and applications in the National Archives. The Smithsonian has a bunch too.

Even foreign patents, I got all of BMW and Focke Wulfs on one of my visits.

So we can all look forward to you sharing this data so we can all draw our own conclusions? or are we just going to get your assurance you've seen it and done the maths and we can take your word for it?
