He was practicing, along with the other pros.
Crashed, landing a long table top.
Several other pros landed on his body.
N8 likely died from his fellow racers landing on him, which is why it's a bit hushed.
Note, what happened isn't the fault of anyone else. There's nothing you can do about your landing when someone has a yard sale on the backface of a 90' table.
I recall watching Nate Woods and Destry Abbott battle it out in the WORCS series, as Team Green teammates, after I was done in the amateur class.
Nothing against Nate, but I was always rooting for Destry.
There are fast bikes, then there are really fast bikes.
