The FAA works at their pace. How true this is, here's an example. 2 months ago I got a letter from the FAA. Clearly something was wrong so I had to call and call all the way to Oklahoma. After review it was determined it was an error on the FAA's part, but I need a letter saying that to finish what I was doing. 2 months ago I still have no letter, but every time I call they tell me what I want to hear...oops its all our fault, we'll get the letter out as soon as we can.
