OMG this is so funny in so many different ways of viewing it.
A corvette of the German Naval Forces is pulled backwards by a tug into a harbour in London and blasts the Imperial March from Star Wars, as happened seemingly yesterday.
This is not serious

new motivation for drone usage?
Who would have come up with 15kV at 16.666 Hz?

16 2/3 is one third of 50 Hz which makes for simple frequency conversion with a rotary (motor-generator) converter. You want AC for easy voltage conversion at the same time as low frequencies were good for the old traction motors.
As for 15 kV… I guess it was seen as a good compromise when it was introduced 112 years ago in Germany.
16 2/3 (or 16.7 Hz) 15 kV is the standard in Germany, Switzerland, Austria, Sweden and Norway. Most new systems use 25 kV 50 Hz. With modern power electronics there is no reason to use a frequency other than the normal grid frequency.
When ATC is taken over by spiders…
Both Nice and Cannes were closed for a while this morning with thunderstorms directly overhead. There was a lot of creative holding going on. I think this guy gets some kind of prize. He did finally land at LFMD a few minutes ago.
