Airplot is a scheme dreamt up by Greenpeace to scupper plans for a third runway at Heathrow. They’ve bought up land on the planned site (not quite on the runway itself, but near) and will refuse to sell it. I think the idea is that everyone named as a co-tenant/owner of the land will have to be approached by the Government when it comes time to start buying up the land, making the job particularly hard.
This page has been through a number of changes from the original planned layout. Originally it and the next page were going to be a cut away to reactions in the White House to stuff dropping out of the sky. However that was going to mess with the flow of the two pages after that, spoiling what will be a big reveal in the printed version. So it became our heroes being tossed about as the spaceship hits. The hit was originally going to need art only in the top left and bottom right corners, with a fade from white to black and back again in between. Eventually I ended up with this page.
