I think there was the former Secretary General of BALPA and at least one airline pilot, so not quite accurate.
This program , & the contributions from the listening public contained within it, was a complete load of bullsh*t. They didn't have anyone on it who knew anything about the subject, & no one who could explain where we stand technically today & how this would all work out. All it consisted of were one or two people who had connections with victims of air crashes & a few meaningless anecdotes to share. It was all pointless nonsense !
