Zaha Hadid was once flying to Frankfurt to give a talk. Her plane taxied out, developed a minor fault, and stopped. She refused to believe the reassurances that the delay would be brief, and demanded that she be put on another flight. Her wish was impossible — to return to the stand, to unload and reload her baggage in the hold, it couldn't be done — but Hadid insisted, vigorously. The crew tried to calm her, warn her, admonish her, until a stewardess noticed that this was the same woman whose picture was in the current edition of the in-flight magazine. Are you Zaha Hadid? she asked. Then the impossible became possible, and the architect got to change planes.
