There were mitigating reasons but in essence, you are correct. I took a load of photos
on the fuel panel about 2 hours post crash and had them developed (pre digital) straight away. I took the pics to the hospital to show the pilot and he just said how stupid and simply said 'My mistake Boss'. The aeroplane had done two Guernseys with another pilot and then lost both its engines on this flight. If you look at the amount of fuel in the tip tanks that would be correct ie Jersey to Guersey twice and then the tips would only to another 15 minutes if you were lucky. In fact he was lucky as it happened over land. The previous pilot had half moon glasses and proved to be as blind as a bat on anything overhead - where these switches actually were. Without doubt, and the CAA said the same thing - that the switches were operated by a previous pilot. When I dug a bit deeper , I found the 'previous pilot' had done something similar on a similar aeroplane in the Indian Ocean when flying for the local airline. In Jersey, when he cooked two Starter Generators on a Bandeirante I just asked for his headset and ID card. He attempted to take me to an Industrial Tribunal which was so funny it beggared belief. ( He accepted that he made a huge mistake and came into my office to say he would pay for the brushes in the generator [obviously he didn't understand how they work] and if I put the bill in his mail drop he'd give me a cheque.) We lost that aeroplane for two days service, we night stopped 20 passengers in Jersey and the bill for the spares was £38,000 plus the stripping and fitting.
I was pleased to terminate him.
