BA 38..jury out..mate operated the first service and wrote to his manager about the intense cold over Siberia..told not to worry.
Apparently the fuel wasn't allowed to settle after refuelling before the water check in Peking.
Crew ignored the planned descent into warmer warmer in the later stages of the flight.
iirc no fuel heat.
On the iron duck we had different min fuel temps depending the type uploaded.
Could have been either ice or wax but what is definate it didn't put BA in good light.
