Most of the 146/Avro RJs are stored with the intention of being returned to service. Two of the former Azzurra Air machines are going to Euromanx - one is parked northside in Euromanx colours. Another has been delivered to the Bahrein Defence Force. Some have been parked so long that I think that scrapping may be the only option though!
That storage area is also used by Flybe engineering to park aircraft that are awaiting collection by their operator after maintenance.
