Path: StraightLine/Flyby
% Compute the payload fraction for a straight-line flyby (fminbnd).
This for a constant thrust, constant exhaust velocity rocket. Computes
the payload remaining at a given distance. For a flyby, this is a simple
bounded problem using the distance equation. From here, the power or
payload mass can each be found from the other, and they are proportional
to each other.
The distance must be less than the "zero payload distance".
