"Doncaster Council had to deal with an abandoned speed boat last year."
Bullseye has a lot to answer for.

in the days of analogue telly, we were covering a football match for MOTD as we did most weekends. At the time I was a vision engineer and during the match our main function was exposure and colour matching of the cameras. The cameras themselves were Philips LDK5s, which had a Camera Control Unit and power supply unit in the truck. The PSU was basically a big FO transformer (and some electronics in a separate narrow unit) and two fitted side by side in a ninteen inch rack. They had one control on the front panel, an illuminated push on push off switch which required a decent bit of force to operate. They were mounted just above floor level.
Being Philips, there was a guard around the switch to prevent accidental operation. Being Philips they often bent or fell off. The engineer sitting next to me, let's call him Billy, was bored with the game and had a mid-half stretch which included his legs. We all heard an ominous 'click' as his size nine planted firmly on the guardless switch, and laughed as we knew what was coming next. The switches didn't change state until released, so Billy had to spend the remaining twenty minutes of the first half keeping the switch pressed in and therefore the camera operational.
How we laughed.
In my wage slave days I used to work as an outside broadcast engineer for a world famous broadcasting corporation based in Britain. An upstart satellite company used to pitch up at sport events and ask for a feed of the core coverage and 'black and burst', a video timing reference signal which as its name implies consisted of sync pulses, a colour burst and black. Plug it in to a monitor and you got a black screen. We gave him a couple of video leads with the signals and off he went.
Just as we went on air he came into our truck and reported "There's pictures on the reference wire and nuffink on the pictures one".
True story, it happened to me. Not a mate's mate but actually to me.

As my dear old mum used to say in her broad Irish accent; "You can tell what God thinks of money, look at the people he gives it to".
To measure something with an accuracy of 13 parts per billion, how accurate do the parameters used to make the measurement have to be?
I'm thinking of the current in the current balance for instance. Is it possible to measure a current to a sufficient accuracy? Or the velocity of a moving coil in a known magnetic field. How accurately is it possible to measure both the coil's velocity and the magnitude of the field?
