Surely anything short of reaching orbit is suborbital?

• garmaine 6y ago
  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.
