Finally we're getting some anecdotal info. related to CF bike frames used in the cold. Additionally, comparing commercial CF airplane wings to CF bike frames may not be the best apples-to-apples comparison. I would hazard a guess that airplane wings are designed to very different standards, as well as a undergoing rigorous / professional maintenance protocols.

On a operational note - I like my CF frame in the cold because the frame doesn't care too much about salt on the road, nor does it transmit the cold to my bare fingertips. I haven't thought twice about taking any bike out in the cold other than thinking I'm going to freeze my cahones off.
