It is interesting that a "large swathe of TREs" voted Brexit, although the intention to leave EASA was never revealed during the vote, I cannot understand why someone with that level of insight into the airline industry would vote for a process that would hinder international trade and want to damage the profitability of his/her company. If these TREs are at a scheduled carrier, what would be the point of harming a business that earns it's living flying Europeans around Europe?
If this really is the case, I'm not sure being a TRE necessarily qualifies an individual as being politically astute.
