Lakenheath isn't too far away from me (about 80 miles at a rough guess). We occasionally get planes from there fly out here along the coast to do training over the North Sea. I guess another British term I should have mentioned is "aeroplane" for airplane.

Going a little more on-topic for electrics, the British Standard symbols for electrical fixtures on architectural plans are also different to those in the U.S.

A few electronics symbols are also normally drawn a little differently, such as that for an electrolytic capacitor.

Oh yes, here's a question for you all:
What do you think I'd be about to do if I'd just bought a silencer?
