Reckless dive

The humming of the hypermagnets broke past the level of mild noise and entered the stage of a painful experience. 

The high-pitched, grinding noise went right past all of my defenses, penetrating right into my brain and drilling into it as if the maglev's designer was actually an unfulfilled lobotomists. 

It lasted for but a second, though, for the very moment we suddenly sped up upwards off the cliff, the distance between the magnets and the ground below spiked. 

The noise of the electricity flowing through the machinery at a rate that brought it to its manufacturer-specified limits was still there, but the piercing, high-pitched sound of some sort of resistance decreased down to a bearable level. 

Quite interestingly, though, even though we went right off a damn cliff… The hovercraft continued to rise even higher up.
