Thanks for all. Please note that in the hurry did not yet give the proper credit for all those who rightfully deserve it, above all to our dear Member George. And there's still a lot to do with formatting and spelling mistakes. Unfortunately, I have only one life to live, so either I correct those or add new material, can't do the two at the same time.
BTW, one of the next updates will be the French PERFORMANCE trials on 109E WNR 1304, which yielded very close to the V15a prototype results, as 570 kph was measured at critical alt.
Until then, there's another small update for today.
