Heathrow terminals 3 and 4, as well as Gatwick south terminal have all been closed for several months and not likely to reopen any time soon
Does anyone have a link to a video (maybe from a small drone) of the interior of these terminal in their closed state ? I'd be interested to see what they look like - all covered up with dust sheets (?), and shops shuttered, and then compare them to how I remember them from 2019
