Oh, and I'd DEFINITELY interfere with the main storyline. I'd probably fly either
A) a modified version of the Hindenburg with an onboard, portable mooring tower, a much stronger hull, and propfan engines to more than double the speed
OR
B) a VTOL MD-11
as my primary method of getting from place to place.
I'd also use a Smith and Wesson Model 27-2 as my primary weapon. Aside from conventional .357 Magnum ammunition, I'd also fire containers, which are basically cartridge-shaped bullets that open upon impact with the target. They'd be loaded with either holy water or hellfire, depending on target. Loads could be quickly and easily changed miraculously.
