Easy to train
ATCO’s could be fairly easy to obtain and train if there are plenty that have been made redundant. Just like a pilot that doesn’t have to go back to their basic training and do a PPL an ex ATCO returning to the same unit perhaps would take a relatively short time to revalidate after a year or so off. I sincerely hope it doesn’t come to this but let’s not be too complacent and let’s try to be prepared for all the arguments and possible threats that may come our way.
