they are doing it on purpose. Peel want to close the airport so they can use the land.
The word on the street is that the 737 that arrived for scrap has not yet been scrapped due to numerous hurdles (wether they were put there by the airport or not I don't know). Two or three other aircraft have gone elsewhere during this time.
Now if I were running that airport I'd be bending over backwards to get this working and have a positive bit of news around the place, but that doesn't seem to be the case.
