HUY,
would that be KLM Engineering then? -KLM do the large majority of their own engineering and maintenance and all their own heavy maintenace unless specialist/one off expertise is required.
For that they have specialist major bases at Amsterdam and Norwich, so that knocks that inconsequetial rumour on the head.
That rules them out, so who else could the airport be offering a large shed for minimal rent to?
Pikies, rave organisers, fill it full of sand and it could be Cleethorpes 2 (the Winter alternative), or perhaps like the rest of the airport, it will be a superb facility without hope for the future.
