So, tell me again about how that impenetrable airport security is supposed to keep us safe?
From the BBC:
Four people were arrested after unfurling a banner from the top of the British Airways Airbus A320, which had arrived from Manchester.[...]
The move came as protesters were gathering in Westminster on Monday to oppose plans to expand the airport.[...]
Greenpeace said protesters put a banner reading “Climate Emergency - No Third Runway” over the plane’s tailfin at about 0945 GMT.
Is it wrong I feel a sudden urge to hop across the pond to see the site of this nefarious deed, thereby aggravating the problem the protesters were protesting against?
