Two odd things stand out in the report regarding the fuel.
Initial results confirm that the fuel conforms to Jet A-1 specifications and that there were no signs of contamination or unusual levels of water content.
And...
The specified freezing point for Jet A-1 fuel is -47ºC; analysis of fuel samples taken after the accident showed the fuel onboard the aircraft had an actual freezing point of -57ºC.
Is it normal for Jet A-1 to have a freezing temp of -57C? Is this really pure Jet A-1, or is it mixed with something else?
