Pie,
"Do you think there was more than 95 litres remaining?"
I know you directed this question at Sid and I'm not answering on his behalf but, all those of us not on the investigation team can be sure of, is that however much fuel was in the tanks at the time of impact, 95 litres was removed.
If you want some more in depth info on the fuel system, PM me your e-mail and I'll dig out my training notes.
