How the heck do you do quotes in this forum? Clicking the reply button on an individual post doesn't do it.
Anyway, all certification involves demonstrating that the airplane can safely go beyond the limits imposed on the operators, so I suppose in the strictest sense what I said could be seen as incorrect.
