Mon have not been in for training for quite a while, but in the past we have had Mon 767, A320 and A330 equipment in for training flights.
Also lots of other training flights, I guess because the place is underused at present and DSA are glad of the extra revenue.
Regular appearances are put in by Flybe (mainly Emb 195), and now deceased UKI 767. Also Oasis 747’s when the wind at Manston isn’t suitable.
