If you have a distance and the mass of the object that will travel it you can work out how much force it needs surprisingly easy. You've probably done it yourself mentally while throwing a tea bag in the bin.
Of course lives are at stake here so they probably used a pencil and paper and had someone check it.. maybe two people.
Those Red Bull guys just use more paper and people.
