With Bubba Watson apparently weighing 82 kilograms and the revised Martin Jetpack specifications stating a 100kg payload, Bubba would still require his grass bound caddy to move his equipment around the course, as the remaining 18 kilograms of allowed payload would be taken up by 18 litres of fuel. He also would not get all that far with this, considering how much fuel is required for take offs and landings. So, what other purposes could be found for the Martin Jetpack? I can't think of any right now.
