I would think the fuel in the competition aircraft is only enough to complete the race, with a bit extra for go-arounds and delays but not much.
You are probably right. My heart goes out to all those injured and killed. I hope the death toll doesn’t climb any higher but I fear it will. As far as the rescuers, it would take nerves of steel to walk up on that scene. I honestly don’t know if I could do it, knowing what I would find.
Yep. Anything above that is just extra weight to haul around.
