There's the old story about the Blackburn Beverley crew who were asked to confirm their gear status, the reply was 'down and welded'

'
Same thing on the Wessex! Guetersloh always advised us that our DECCA letdown to the runway would be radar monitored, caused a moments silence once when we said that their GCA would be DECCA monitored.
