Ah, I wonder if there was an archive of those codes anywhere. They used to
publish it in the old AA books, but I threw that away years ago.
I often used to while away the tedious journeys as a kid looking for local
plates (AL and NN etc.) and special numbers.

We had LNN 31.

Surely Bill you would have followed ET (sic) for Rotherham?

Much obliged.

Looks like we are stuck with the (horrid) present system till 2049 at least.
I doubt I'll care much by then.

We also had RET 406. Both vehicles were old ambulances. LNN 31 was a 1948
Morris and RET 406 was a 1956 Bedford.

These are the two geosynchronous reporting satellites, which for ease of use
in the system are treated by receivers
like regular GPS satellites except they **for some reason** don’t seem to
move in the sky.

**what part of "geosynchronous" does the author not understand?

Geostationary is the usual term for objects that don't move their apparent
position in the sky. Geosynchronous ones do move, but are always in the
same place at any particular time every day.
All geostationary satellites are geosynchronous - the reverse does not
necessarily apply.
Geosynchronus is, IMHO, more usually used only for non-geostationary
satellites, even though technically wrong. Perhaps this is what the
author doesn't understand.

Researchers have cracked the puzzle of how pigeons find their way
home: they just follow the main roads.

Interesting ... I was expecting that to be dated 1st April, but it
wasn't.

I wonder whether the reason is that the birds just retrace the path
by which they were taken (presumably in a vehicle) when they were
released?

Cheers,
Daniel.
