130.4 - Here's rough guess. You get a problem with the window, you read the checklist and probably find out that you get a speed restriction and have to avoid icing conditions. The more knowledgable Boeing drivers will, I'm sure, put me right. Then, as you have no imminent danger, consider other any operational aspects and then ask the company what they would prefer. Thomson, being a fairly nifty operator, determined that Bordeaux would be a good place for a rescue, the crew agreed and diverted there, "tuit suite".
Of course, I could be totally wrong. Maybe they were about to tailspin or something and the mobile childerens school, church, hospital and old people's home were all on their way to the scene of the impending crash.
