I'm also guessing that the name 'heaviside' is a reference to the Heaviside step function. Which of course, looks like a vertical takeoff, and implies that this project is a "step function" in flying transportation, etc..It's a pretty great name.

The function is named after the person.

I realize that. I'm suggesting that they chose to name it after this person because of his association with the function, and it's evocations.
