"Top Gear"/"The Grand Tour"'s James May drove a Bugatti Veyron on such, hitting 259 MPH on it's 5 mile straight.

Since it's introduction in 2002, it's the most advanced artillery piece in existence.
US Army/Marine gunnery crews - along with info via a forward command post - determine the firing of the 155mm shells using wind speed, air temperature, and curvature of the Earth.
Omission of any of these three factors from their calculations, and it's guaranteed that they'd miss the target.
Moral: Considering the facts, no 'Faith' required.
