# What is the procedure for a rejected Jet/Rocket Assisted Takeoff (J/RATO)?

Seeing the image of a Lockhead LC-130 doing a jet assisted takeoff in snow mentioned in this answer, I wonder:

What is the procedure for a rejected takeoff when using JATO? Can the JATO rockets be turned off once ignited?

So, you either reject before igniting the rockets or you don't reject at all. As per @ratchet freak's comment, $V_1$ is when you hit the button, which may be as low as $0\,kt$, depending on the specific application.
