My vote for understatement of the decade:
The sheer volume of our aviation regulations shows that there has been a problem in the approach used in the past.
Ya reckon?
And they're about a quarter of the way through the process. However, because of the problems in the "new" regulations already made, projects to fix them will mean the program won't finish in the year 2075 as projected, but instead a considerable time after that.
Let's hope the rules are enforced "nicely" until at least then.
