Scottish flag - Skywatch Friday
The Scottish flag, or Saltire, is an X-shaped white cross on a light blue background. It represents the cross on which Saint Andrew, Scotland's patron saint, was crucified. Dating back to the 12th century, it's one of the oldest national flags of any country. (Edited to put on this link to the Scottish flag, to show the real thing).
With Saint Andrew's day about to be celebrated on 30 November, these crossing con trails seemed an appropriate Skywatch post for this week.
