A big cruise-boat needed to pass under a 400 kV line on the river
Ems and to avoid trouble the turned it off during the passage.

In the western half of Denmark the frequency got up to 50.4 Hz before
producers started to fall off the net.

Never attribute to malice what can adequately be explained by incompetence.
