I'm another who will vouch for this worthwhile visit to Swanwick. Attended last year and look forward to putting my name down again this season. These are our everyday colleagues yet our respective environments are completely different. It is valuable to be able to bring our perspective to their emergency training - in the long run it's for our own good too.
And further to a previous poster, also think that a few more ATCOs on jump seats would improve mutual understanding.
