This untapped wealth of water has enticed scientists and entrepreneurs for over a century. There were 19th-Century plans to deliver it by steam-boat to India and to supply breweries in Chile. In the 1940s, John Isaacs of the Scripps Oceanographic Institute recommended towing an iceberg to San Diego to alleviate a Californian drought. In the 1970s, Saudi Prince Mohamed Al-Faisal wanted to haul an Antarctic iceberg across the equator to Saudi Arabia, and sponsored two international conferences on the subject. The EU received proposals in the 2010s to haul an iceberg from Newfoundland to the Canary Islands.

Airbus' newest airplane to enter service is a technological marvel to behold. It can cruise on autopilot mode with state-of-the-art controls.

If you have ever wondered what all those switches, dials, and levers do in the cockpit of an airplane, you are not alone. CNN Travel asked the pilot of the aircraft, the Airbus A220-300. The pilot, Gerhard Ramcke, of Latvian airline airBaltic, gave the channel network a tour of the flight deck of a brand-new Airbus A220-300 as the aircraft launched earlier this year, according to a CNN feature.
