New rules should limit designs to high performance aircraft that actually were deployed on carriers.

No light observation planes that could land anywhere.
No one-off sales stunts like the Mustang and the Airabonita.
No German fighters that might have flown off a carrier that was never built.
No land planes that were launched from carrier with no return.
No land planes that made an emergency landing of a carrier.

That still leaves plenty of genuine US, British and Japanese designs.

There should be an exception for anyone crazy enough to enter a four engine C130 in a carrier event....and with no hook no less.....
I've never entered an event but if I do it will probably be in something like a Guardian or Mauler with a .40 or .65...although I do have a couple of other carrier planes in process for the last 15 years.... I'm such a slacker... 

Since these comments are a year old, I assume nothing came of these particular proposals?
