It was cool to see all those 737s parked everywhere at Boeing Airport. I'll be glad to see them go and I hope I'm there when they do. Before you Airbus fans get on my case, I'd say the same thing if I were in Touluse and Airbus were back from a strike. About the question, they have to find those faulty bolt holders, and do their usual job, so it may go slow for a while.
