Jet fuel freezes at -40*C. Even Jet-B fuel (70% gasoline) freezes at -60*C. It's not uncommon to see -50*C on the ground during the winter in Alaska. Even the best synthetic lubricants are nearly solid at these temperatures. It's not hard to ruin machinery due to a lack of lubrication and brittleness of everything. Rubber boots shatter like glass if you drop them on concrete. Hydraulics stop working at about -40*C. Oil seals shrink and can cause problems too.
was all that smoke starting fuel??

-28? That's warm. Last flight I took it was -50*C. I don't think they shut down the engines at those temperatures.
