I remember when the GP system was just being set up - not all the
satellites up, or something - being shown with some pride by a colleague
at work a GPS receiver; it was a full-size PC plug-in card, and he had
what must have been an unusual laptop as it could take such a card
(though only one). He proudly told me - with a twinkle in his eye, he
was like that - that B block, the building we were in, was proceeding at
X knots in a ?erly direction.

The trouble with the death penalty has always been that nobody wanted it for
everybody, but everybody differed about who should get off. - Albert
Pierrepoint, in his 1974 autobiography.
