I had a dream about an airline offering full wireline internet connection on its aircrafts. Each aircraft is equipped with a router which is connected to the ground through a 10000 Km Ethernet cable (with embedded signal amplifiers every 100 m ca.) . Such cable is progressively unrolled from the plane during the flight, e.g. from Copenhagen to Chicago.
Kids are literally astonished by the biggest kites they will ever be able to see in their entire life.
