Nitpick, 12km isn’t quite suborbital.

[Doxin]

Surely anything short of reaching orbit is suborbital?

[garmaine]

As an industry term, "suborbital" implies space flight, which means crossing the Karman line (100km). Fast enough to exit the atmosphere, but not fast enough to achieve orbit.

The 12-ish km of this test is within the operating ceiling of most commercial jet liners. This was an atmospheric test of an orbital-class rocket.

Where does suborbital begin? If i throw a ball, it's a suborbital flight.

The most common definition of suborbital flight would be a flight that reaches space (Karman line at 100 km) but does not reach orbit.
