So, "World's greatest, ever" sits very well with me as a description of Eric Brown
And originator of the worlds greatest myth aka the X-1 had to be modified to incorporate the M.52 tail in order to get through the barrier. Somewhat detracts from the memory of a great man and pilot. Came to the conclusion his myth came about from two countries being separated by a common language, to wit, what is a "flying tail". Winkle had one definition, the Americans another.
