13. The ocean surface current in the Indian Ocean close to the equator is around 1 to 2 knots. A drifting object in the water around the equator can shift between 26 to 52 miles a day (728 miles in 14 days). But around 200 miles further from the equator, the current is much weaker at less than 0.5 knots.
14. A Boeing 777-200 is 70 yards long and needs at least 4,000 feet of runway to land safely. But the plane would not be able to take off again on a runway of that length.
15. Many pilots use flight simulators. They can be assembled at home and range from simple software on personal computers that can be purchased off the Internet for $30, to sophisticated full-motion simulators for professional pilots, which cost thousands.
17. A pilot's experience is calculated in flight hours. The Malaysian plane's captain, Zaharie Ahmad Shah, had more than 18,000 flying hours. Most major airlines requires pilots to have at least 2,500 flight hours under their belt, while regional carriers generally require a minimum of 1,500 hours.
