There's a whole snowball effect. Tesla is doing the same thing with the electric car.
By the way, outer space does begin at 100 kilometers.
At 100km it is dark and cold but there is atmosphere.
That's not "space" in my book.
You are, of course, entitled to define "space" however you want in your own book, but be adviced that a lot of people will disagree with your definition.

The Fédération Aéronautique Internationale has established the Kármán line at an altitude of 100 km (62 mi) as a working definition for the boundary between aeronautics and astronautics. This is used because at an altitude of about 100 km (62 mi), as Theodore von Kármán calculated, a vehicle would have to travel faster than orbital velocity in order to derive sufficient aerodynamic lift from the atmosphere to support itself.
It's just a high flying plane.
Its max altitude is still within the outer limits of the earth's atmosphere for pete's sake.
It can only hit 100km (62 miles):
International law defines the lower boundary of space as the lowest perigee attainable by an orbiting space vehicle ...
Due to atmospheric drag, the lowest altitude at which an object in a circular orbit can complete at least one full revolution without propulsion is approximately 150 km
