It may have broken up below the karman line, but space isn't a hard cutoff. The atmosphere was still far too thin to not need a pressure suit at that altitude, and both missions failed due to problems that would come into effect upon performing the re-entry maneuver.
Correct. People have died on the way to and back from space, but never in space. So in terms of human deaths, 100% have occurred on earth or in its atmosphere.
