Police motorboat collides with a ferry cable and does a backflip in Timár, Hungary, 3rd of August 2024.

The captain did not realize the cable belonging to the local ferry is in the way and hit it with high speed. The boat belongs to the Hungarian police forces.
Update: Only one person was on board and he survived. The boat sank and the responding forces pulled it out of the water successfully using a larger vessel.
Looks like the captain ignored the basic rules of approaching the ferry crossing carefully, also did not care about the signs on the side. Investigations are ongoing.
Clarification: The rope (or steel cable) can't be marked by flags etc, since the ferry uses a mechanism that kind of goes on top of it to drag itself from one side to the other.
The Captain of the Hungarian Police unit said: “These cables are usually only up when the ferry is in operation. Regulations require that the crew operating the ferry must be verbally requested to lower the cable by the passing vessel. The officer failed to request the cable to be lowered. There are also many warning signs, lights and flags before approaching.”
When the ferry is not in use the rope gets submerged in the water to let boat traffic pass.
