I’m a World War II fighter, flown out of Japan;
In Producers and Forum, their films’ leading man;
I am nothing to speak of; hone in from a span;
And the hour we go, as described by the plan.
Who am I?
UPDATE (1/12/15): Nothing yet? Zip? Zilch? Here are some more clues:
I’m the Ground of New York 9/11 attacks;
The original Patient who plague first contracts;
I’m the Dark Thirty prefix, as Jessica acts;
And this blog’s total readers, when postings it lacks.
Now, who am I?
UPDATE (1/14/15): Still nothing? Nada? Goose Egg? Here are some more clues:
I’m a Schoolhouse Rock hero; a diet Coke name;
I’m the green on the wheel; a dress size with thin frame;
I’m a white-colored candy bar; sum of a game;
And this riddle’s times three, but my value’s the same.
Okay, now who am I?
