While this shyt happens time to time, I wonder if this guy got complacent. If I did this for a living, I would ensure everything is working before each jump. If something isn't right, don't take any chance. Have a thorough checklist of what needs to function; anything, a small cut even, and the jump is cancelled.
Some people though get so caught up being excited about filming a GoPro, that they overlook a vital element or just say, "I'll check it next time." and then they die.
And the fukked up part, tomorrow is a another day, and your dead. All that clout chasing and living in the moment don't mean shyt if your dead, because someone else will fill your spot.
