Can't decide what I think of think of especially as there is some debate as you whether its actually reach space.
Apparently there is a thing call the Karman Line which defines where Space starts and Branson's venture doesnt cross that
Should we be surprised a craft call Virgin didnt make it all the way? [Post edited 12 Jul 2021 11:37]

The edge of space is not a precise boundary, hence the debate about at what altitude it sits. Karman himself originally defined it as just above 80km, around the height that Branson's vessel reached.
The US has always gone with 50 miles (80km*), the FAI 100km (62 miles). The atmosphere actually extends well beyond that, just getting thinner and thinner all the time.
For orbital flight, this is largely irrelevant, as you can't circulate that low without the drag slowing you enough to fall back to earth. It only matters for sub-orbital lobs, which are just a matter of prestige.
I would say I have a bit more respect for Virgin and SpaceX than Bezos' efforts, as both the former two (especially Musk) have produced semi-reuseable, relatively cheap satellite launch systems, rather than only doing ultra-expensive space tourism.
* My typo, meant 80, not 62 [Post edited 12 Jul 2021 13:01]

We need a proper boundary.
And a wall. |  |
