An Aeroflot Airbus A330 landed at LAX while I was shooting there.  On plenty of occasions, I have seen ice on the underside of the wings of landing aircraft where the cold fuel remaining in the tanks has caused condensation and freezing in the warmer damp air lower down.  However, I haven’t ever noticed it on the fuselage structure.  On this jet, though, I could see ice on the surface and the patterns of ice reflected the underlying fuselage structure.  Maybe this is there more often and it was just the paint finish that made it show up this time.
