ThePlanesHaveStopped

#ThePlanesHaveStopped was a hashtag used by the students of Coal Hill School online on news sites and Twitter on orders by their teacher Clara Oswald when planes all around the world seemed to have frozen in mid-air (which was actually a time stop created by  to catch UNIT and Clara's attention when the Twelfth Doctor went missing).
