Out Of Control Ice Drill Subdued With Children’s Chair

This is a video from some ice fisherman who, in the process of trying to drill a fishing hole, wound up with their auger stuck in that hole, rapidly spinning its engine on its own. Thankfully, the fisherman are eventually able to subdue the drill with a children’s chair. But why was the drill stuck on in the first place? Is there not some sort of safety mechanism that prevents the drill from operating when somebody isn’t holding it? Or was that safety mechanism frozen or disabled or bypassed? I’m genuinely asking, because I’ve never drilled an ice fishing hole before because I have no interest in living somewhere so cold in the winter that the lakes freeze and you can drive your truck on them and drill holes in the ice and sit around fishing through those holes.
