Model Airplanes

A turboprop plane headed from New York to Florida stopped responding to radio calls and veered hundreds of miles off course — prompting a chase by two F-15 fighter jets — before crashing off the coast of Jamaica Friday afternoon, the Federal Aviation Administration said.

The pilot had been spotted “unconscious and slumped over” in the cockpit, U.S. officials told NBC News. NORAD, the joint American and Canadian air command, said on Twitter that the people on board might be suffering from oxygen deprivation.

The plane was registered to Rochester, New York, real estate developer Larry Glazer. He and his wife Jane were the only people on board, their son, Ken, said.

Jamaican Defence Force dive teams have found a wreckage field in the water near where the plane went down, about 14 miles off the coast of Port Antonio, the military said; the U.S. Coast Guard has also launched a mission to the area.

The plane, a six-seater Socata model TBM-700, took off just before 8:30 a.m. ET from Rochester and

Boeing forecasts China will lead the Asia Pacific region in new airplane deliveries

Theodore Koumelis – 05 September 2014, 06:15

Boeing ‘s annual China Current Market Outlook (CMO) shows Chinese carriers will take delivery of nearly 45 percent of the total demand for airplanes in the Asia Pacific region during the forecast period.

“To compete in the tough long-haul international market, our Chinese customers are focused on evolving new business models, adding new destinations, increasing their capacity and resources,” said Tinseth. “These trends will shape market demand for an airplane lineup that has high efficiency, low operating costs, environmentally progressive technologies and a great passenger experience. We believe Boeing’s comprehensive widebody portfolio is perfectly aligned to meet those needs.“

Today, Boeing jets are the mainstay of China’s air travel and cargo system. More than 50 percent of all the commercial jetliners operating in China are Boeing airplanes. Some 8,000 Boeing airplanes fly throughout the world with integrated China-built parts and assemblies. China has a component role on every current Boeing commercial airplane model – the Next-Generation 737, 747, 767, 777, as well as the world’s newest and most innovative airplane, the 787 Dreamliner.

Scientists have taken a closer look at the ancient past of Greenland to find out a bit more about the landmass’s climate. By studying three ice cores, scientists have found that there was warming of the large ice sheet at the end of the last ice age, resolving a long-standing paradox over when the warming occurred.

About 20,000 years ago during the coldest parts of the ice age, large ice sheets covered North America and northern Europe. Global average temperatures were about seven degrees Fahrenheit colder than during pre-industrial times. Then, a shift in Earth’s orbit increased the solar energy reaching Greenland and about 18,000 years ago, a release of carbon from the ocean led to a gradual rise in atmospheric carbon dioxide.

Surprisingly, though, analysis of ice cores in the past did not show any warming response as would have been expected from an increase in CO2 and solar energy flux during this time. That’s why scientists decided to investigate this particular paradox a bit more closely.

The scientists reconstructed air temperatures by examining ratios of nitrogen isotopes in air trapped within the ice instead of isotopes in the ice itself, which had been used in past studies. In the end, the researchers detected significant warming in response to increasing CO2.

“The Greenland isotope records from the ice itself suggest that temperatures 12,000 years ago during the so-called Younger Dryas period near the end of the ice age were virtually
