I have read the latest AAIB report.
Water content of the fuel seems to have been established from fuel samples after the crash.
According to the AAIB and other reports, most of the remaining fuel was spilled and only a few tons remained.
Somebody, many hundreds of posts ago, suggested that, with water being heavier than fuel, under the circumstances a lot of water could already have drained from the aircraft by the time the fuel samples were taken.
Question: might there have been a lot more water than quoted in the AAIB report?
