The pilot scheme is being implemented at some busy airports that have many international flights. Each week thousands of foreign pilots and cabin crew have to use these airports to do their jobs. Presumably all of these foreigners do not qualify for UK national ID cards. If they can be allowed to access the secure areas at UK airports without the new UK ID cards then it is impertinent to impose the requirement upon UK citizens going to work at airports within their own country. That would also show how unnecessary the requirement is. There’s obviously a hidden agenda!
