In the mid-1950s Westlands serviced and tested Sabres at RAF Merryfield. Typically, they got behind in their work and started doing full power engine tests at the weekend....
As we lived less than half a mile from Merryfield, this rather annoyed my late father. After the first weekend's disturbance, he managed to obtain the private phone number of Westlands MD.
So the following weekend, when the racket started again very early in the morning, he rang the MD's number: "Hello, did I wake you up? Well, hard luck - because you woke me up!".
Next weekend, the noise started again. So Westlands' MD got another early morning call: "Hello, it's me again!".
The following weekend, all was peace and quiet....
