"THE GREAT GAZOO"
If it was able to be documented, early encounters with Trans sonic and super sonic flight should be counted, the problem is when first encountered few lived to tell about it.
One thing that many of these early reports had in common was the reporting of the nose dipping, commonly called super sonic dip. This was common on many 1st generation jet aircraft when exceeding the speed of sound. The nose would dip, there would be a loss of elevator effectiveness, then everything would "straighten out." This was mentioned in some of the ME-262 pilot reports, both by German and American pilots. The only way you're going to experience super sonic dip is to go super sonic, or pretty darn close to it!
