I think I know what it is...

It's either a vast conspiracy for O.S. to cook their engines so they can sell more of 'em (or parts )

Or...

They're in cahoots (sp?) with the airplane manufacturers...right darock? I mean now, you gotta go out and buy new airplanes just to go along with all the extra props, and the engines they will need to spin 'em...right?!
