Don't complain about journalists openly asking questions here (can't be more open than calling yourself "theguardian"). Good to see a journalist looking for informed opinion, rather than publishing misinterpretation as usual. Unfortunately I know nothing of the incident, though it sounds very much like the aircraft was treated like every other, rather than deliberately obstructed as a protest. This would however annoy many members of the current government, who feel themselves to be exceptions to all the rules and their own advice.
