They would examine the filter for evidence of metal filings which typically indicated bearing damage. No metal = no need for further investigation. Obviuosly the engine flown for 49.5 hours with repeated cycling of 12 and 4.5lb boost never showed evidence of bearing damage, or they would have stopped the trial.

Man engine and airplane are strategical assets in a war. Not so much men
This why you've got disciplinary council and your superior makes good or bad report on your behavior. This was not paparazzi on look. Think that the logistical bckgrd to sustain a full air-force at war was simply enormous. You don't want to change an eng because some fighter jock only wanted to buzz Lili's home.
May I remind you the late war LW with thousands of a/c build each month but with only hundreds on the fronts?
Even in the late war Tempy the Emergency power had a restricting safety link.
The Spitfire during BoB was a wonderful aircraft, potent, powerful and survivable. That's it.
