Had an interesting Murphy several years ago with could have started anywhere in the supply chain.
F4 out of the shed, linney's did the compass swing but no why could they swing the standby compass. They changed the compass; no deal.
They called me in and, by a stroke of luck we had Alan Snowball from the Greenwich Observatory (I think -what a job for a flt lt). Anyway he had a little gizmo, a magnet in a plastic gimballed cradle.
He checked the F4 canopy arch and found that it was magnetic. he checked further and found the windscreen securing screws were magnetised, or at least some of them.
Then he went to the storage bins and found some of the screws in there were also magnetic. There all looked the same but somehow some were ferous and some were not.
Murphy once again.
