What is official?

SpaceX made history last night by landing a Falcon 9 reusable rocket that had shortly before been in orbital space delivering satellites.

Still, we await the first “official” landing in this mode.  After all, it seems only when it is paid for by the taxpayer can we call it official.  Take last weeks ascent to the heavens by Tim Peake.  It was the “first official” flight into space by a UK citizen.  Never mind Dr Helen Sharman did the same journey to space some 24 years earlier.  But she was funded by the private sector and Russia.  That obviously doesn’t count in some people eyes.
