So we have a capable chap who appears to have acted not so well, partial incapacity would fit this frame. As an old and bold Doc I was interested in the fact that the pilot spoke 'yes' to the paramedic, then was put in an induced coma. Perhaps a lingering symptom of his incapacity may have led the hospital doctors to think it due to the crash injury. Induced comas are not done lightly, yet our man walked out a couple of days later.
