A380 Engine Failure

A380 Engine Failure, (AP) – A look at serious jet engine failures following the Qantas A380 emergency landing in Singapore. Analysts speculated that an “uncontained engine failure” caused the power plant’s housing to disintegrate and damage the wing structure.

—According to international safety statistics, there are about 25 incidents a year involving a jet engine failing either in flight or on the ground. That translates into less than one for every million flights worldwide.

—The overwhelming majority of such occurrences end without incident because crews are trained on simulators to handle the loss of an engine.

—One of the best-known incidents of uncontained engine failure occurred in 1989, when 111 people were killed when a United Air Lines DC-10 crashed while making an emergency landing at Sioux City, Iowa. There were 185 survivors.

—More recent incidents include a Saudi Arabian Airlines 747 after takeoff from Jeddah in July 2008; a Jett8 Cargo Boeing 747 freighter after takeoff from Singapore last December; and an ACT Cargo Airbus A300 at takeoff from Bahrain in April. All ended without injury.

—The most frequent causes of engines breaking up are the ingestion of objects on the runway or birds trikes. Also, mechanical problems such as rotor imbalances can cause microscopic c3cks to form on the turbine blades, leading to their failure.

—In May, the U.S. National Transportation Safety Board recommended more frequent engine inspections to deal with the problem.

China Traffic Jam

China Traffic Jam, In traffic jam 62-mile long in China enters its ninth day, prices for food along the route have skyrocketed. “Instant noodles are sold at four times the original price while waiting in congestion,” said one trucker Global Times. “It bothers me only congestion but also to the sellers,” he joked.

But prices should increase. With drivers stuck on the road, the demand for food increases. The only way that people want most of the foods that are available is to allow prices to rise. What would be better, cheaper food running out or having enough food at an expensive price?
