I'm sure MJ is absolutely right and as Genghis points out, the problem for Cranfield is that they must now be way below the critical mass of movements required to make the airfield viable.
I'm pleased that students will have lost little or no money in the latest failure, but concerned for those working elsewhere at the airport such as re-fuelers and ATCOs. I'm just waiting for an ATC limited-hours move as has happened at other cash strapped airports. My understanding is that even the 'Olympics boost' only totaled about 45 movements, which won't get them far.
The other issue will be whether CFS and Billins will have the capacity to take on the 'new' students - obviously they should have the (ex Bonus) personnel, but aircraft may be a problem in the short term.
It's sad to see the present level of (in)activity, even pre-boom Cranfield used to be a really busy, vibrant place.
