Stevie Ray's death was caused by his schedule, which was made by his management, who could only blame the pilot. What a helpless way to die. Death by contractual obligations.
But you have to stick to schedule when you're a professional, so the fans know you care about them and the music. I guess Stevie Ray should have traveled with his brother, I'm sure Jimmy got to the gig on time. But how would Stevie Ray known that he was about to die?
