Not if it's an Intamin gyro drop tower--those climb up slowly, rotating as they do, and then drop. The vehicles hold lots of people (like up to 80 I believe) and are super heavy, meaning there's no way they'd be able to be thrust upward. Plus, as far as I know (correct me if I'm wrong), Intamin drop towers are mainly powered by magnets, whereas hydraulics are needed to shoot rides up like Power Tower or Dr Doom.
