I find that last bit surprising, no portable defibrillator at Mission:Space? I'm hoping they've since fixed that problem.Polak acknowledged that there was no portable defibrillator stationed at Mission: Space. But she said well-trained, well-equipped paramedics handled the emergency response appropriately. She also said the 44-inch height is appropriate for the ride, and that Disney has no reason to change the ride or public warnings that are delivered through multiple signs and audio and video media. They warn, among other things, that people with heart conditions or high blood pressure should not ride.
I think I will stick to the diet version myself, I don't want to have to start taking physicals prior to my Disney trips to see if I can ride M:S safely or not. As far as taking my kids on it? You can forget about that ever happening. It's not worth the risk as far as I'm concerned.
My thoughts go out to those who lost someone so tragically at the happiest place on earth.
