The difference between endurance and horse racing is simple physics - 
the race horse is going 35 mph  the endurance horse 12.5 mph (12.5 mph 
will buy you a 4 hour 50 and an 8 hour 100).  The energy that has to be 
managed by the horses legs and muscles at 35 mph is 7.84 times tje 
energy that has to be managed at 12.5 mph.  The intensity of the horse 
race is the issue.

The Boeing 787 can be flown completely by computer including take off 
and landing. Of course a man will be at the helm during those times, but 
the control system on board is that good. Many military aircraft are 
being designed to be flown completely by computer. The first autopilot 
system tested - well the plane rolled and would have crashed if not for 
the pilot taking over.

What makes the 787 so good - the number of sensors and the higher 
sampling rate feeding the computer, that is the observability of what is 
going on with the aircraft. The second thing that makes it so good is we 
know now much better how the various sensor payloads react in various 
situations. I believe that we could do the same thing with biological 
systems if we better understood the intricate workings. There is more to 
heart rate - that just BSP as this article points out.

There is information there - how do we use it is the question.
