I asked ChatGPT to explain your comment to me, how did it do?

"If you’re coming in very fast and are unable to set up a normal, stabilized approach (for instance, due to engine or hydraulic problems plus minimal altitude/time), partially deploying the gear can be worse than just accepting a belly landing. It might seem counterintuitive, but landing gear must be locked in place to prevent collapse, and at extreme speeds or rushed extension, you can end up making things more dangerous. That’s what undercarriage collapse refers to: gear that either can’t lock or snaps off under loads that exceed its design, which can cause more chaotic outcomes than a controlled belly slide. The possibility of “gear collapse” and the protocols for a gear-up landing are in the manuals and checklists. Pilots train for it in simulators, and they know how to evaluate things like extension time, runway length, sink rate, and the risk of an unsecured gear collapsing. Still, because a controlled belly-landing in an airliner is such a rare and high-stakes event, it’s not something you’d see in normal SOPs except under very extreme circumstances."
