So how does your point on priority affect the idea that you would be planning to use your assets to the max on what tasks - however routine - you could schedule the day before? - are you saying that this new asset would be sitting around idle just in case? No? I do not see how your comment affects the point that there was nothing, even a mundane training sortie, programmed for the next day.
Perhaps someone familiar with the workload put on such assets in theatre could comment.
I believe that the only other Chinook (HC1) there was u/s at the time.
