Pamplinas,
You asked for any additional information on the Ferronats set-up. I understand that NATS have seconded one of their Gibraltarian controllers to Jerez to take part in training the new controllers. Apparently he is currently undergoing training to validate at LEJR as a tower controller (on a UK licence). Once validated he will be part of the team training the new Ferronats guys. I would be interested to know whether as an employee of NATS (UK) he will be subject to all or any of the new draconian laws applying to Spanish ATCO's. When all the new team are in place he will return to work at LXGB.
