Perks of the job!!
After a bit of troubleshooting on an engine last night I had to replace an air valve. This required a run up to confirm that the problem was fixed. Once the testing is complete, you have to give the engine a five minute cool down phase. Time to get the camera out whist waiting to shut down, that or hold conversation with the guy on the headset "downstairs"........he is not much of a conservationist
