No rules in a knife fight. "Unlimited". Leeward exhibited some instability that was noticed by another competitor, that could not be put down to wind. However it derived, clearly he was at the ragged edge of control.
IMO I think the a/c was rushed into the race, he had little time in it, plus he had shown some impatience to get it to perform well.
At some level, the competition becomes "Jackass IV", with certain injury, and the level of risk well above the reasonable return. "My wings are shorter than yours", "I have the hot set up cooling system", "I'm pulling 140 inches", etc.
The line, the LIMIT, if you will, stretches to a certain point, then crumbles, and people will be killed.
Don't get me wrong, I don't go to RENO to see the AT-6's. Or Sean Tucker. I go to feel the ground shake.
