First, set up a "runway" in any open space about 10 meters long and 2 meters wide and mark it out. One player, called the pilot, stands blindfolded at the beginning of the runway. Their partner, the air traffic controller, stands at the far end of the runway and cannot move. All the other players remove an article of clothing such as a sweater and place it on the runway, or anything else that isn't breakable or dangerous. The pilot must walk the course, arms outstretched like airplane wings, they are guided just by the controllers voice, OK, two steps forward, one step left etc. If the pilot crashes, they swap places with their air traffic controller, the runway is then altered. The new pilot now has to navigate the runway, each time the pilot crashes he swaps with his partner. They play until they make it to the end of the runway. Another team then has a go, the team who takes the least goes wins.
