At the end when the Enterprise sneaks up behind Reliant in the Mutara Nebula and opens fire on her blasting the photon torpedo launcher and blowing her port nacelle off, the visible shaking of the ship was apparent. But when Khan a few moments later activates the Genesis Torpedo, it's standing upright on the transporter pad. Apparently it had been there all along since they beamed it out of the Genesis cave. Prior to the final assault on the Reliant, the device should have tipped over due to all the shaking and vibrations from the phaser blasts hitting the bridge and blowing out the impulse engine blue dome. It also should have tipped over when they entered the nebula because the crew members, especially one, lost his balance and fell into Khan. Don't you agree?
