SpaceShip One nomenclature

[golf_cart_john]

Has anyone wondered at the way the SpaceShip One's carrier is named? They call it the "White Knight". That makes a little sense 'cause it's white, but a knight...
Here's the other half of the picture. Has anyone seen the movie Footloose or heard the soundtrack? There's a great song by Bonnie Tyler called "Holding out for a hero". Part of it goes like this:

...Where's the street-wise Hercules to fight the rising odds? [doo-doo-doo-doo-do] Isn't there a white knight upon a fiery steed? Late at night I toss and I turn ...

Hey, SpaceShip One is definitely a "fiery steed", and they've got a "White Knight" on top of it. The knight's supporting the steed, but it's still odd for a coincidence.

Does anyone know anything more about this, and has anyone else noticed it? I looked around on their website, but couldn't find anything about the naming. This might be a clue to the identity of the guy who's funding the whole thing, the guy they call "The Client". Maybe he (she?) is a Bonnie Tyler fan.

The song and the aircraft could also be named after the same fairy tale. Have any of you heard a little kids' story mentioning a "white knight" on a "fiery steed"? I've looked, but haven't found any using those specific terms.
