The biggest safety threat facing airlines today may not be a terrorist with a gun, but the man with the portable computer in business class. In the last 15 years, pilots have reported well over 100 incidents that could have been caused by electromagnetic interference. The source of this interference remains unconfirmed, but increasingly, experts are pointing the blame at portable electronic device such as portable computers, radio and cassette players and mobile telephones.
RTCA, an organization which advises the aviation (航空) industry, has recommended that all airlines ban such devices from being used during “critical” stages of flight, particularly take-off and landing. Some experts have gone further, calling for a total ban during all flights. Currently, rules on using these devices are left up to individual airlines. And although some airlines prohibit passengers from using such equipment during take-off and landing, most are reluctant to enforce a total ban, given that many passengers want to work during flights.
The difficulty is predicting how electromagnetic fields might affect an aircraft’s computers. Experts know that portable device emit radiation which affects those wavelengths which aircraft use for navigation and communication. But, because they have not been able to reproduce these effects in a laboratory, they have no way of knowing whether the interference might be dangerous or not.
The fact that aircraft may be vulnerable to interference raises the risk that terrorists may use radio systems in order to damage navigation equipment. As worrying, though, is the passenger who can’t hear the instructions to turn off his radio because the music’s too loud.

People across the world use Airnbn to offer their homes to travelers usually for a nightly fee. The home-sharing service provides some people a way to make extra money while they work other jobs.
The company announced recently that one of its most popular professions among American Airbnb hosts is teaching. The information came from an Airbnb study to find out what industries its American hosts work in. the study found that almost 10 percent of U.S. Airbnb hosts in 2017 identified themselves as teachers or in the field of education. The home-sharing service estimated it has about 45,000 active teacher hosts in America. In addition, the study says there are an estimated 75,000 other hosts living in households with a teacher.
American teacher hosts earned more than $160 million dollars from Airbnb in 2017, the company said. That includes about $54 million earned during the summer alone. The average amount earned by teacher hosts individually was $6,500 in 2017. The study did not provide data from hosts about why they choose to become part of Airbnb. But the company noted that many teachers in America face difficult economic situations. Airbnb says additional earnings from hosting can help.
The U.S. Department of Education reported this year that 94 percent of public school teachers said they had spent their own money on some classroom supplies in the 2015-2016 school year. It also reported that the average pay for public school teachers in 2015-2016 was lower than in the 1990-1991 school year when the inflation rate was considered. Some states had even higher rates of teacher hosts than Airbnb’s estimated national average.
Airbnb spokesman Christopher Nulty told The Atlantic magazine that the home-sharing industry was not a total solution for the current problems facing many teachers. But he said he thought Airbnb could be an “important tool” to help teachers make extra money and give them “the respect and dignity” they had earned.
The report on the number of teacher hosts comes as Airbnb continues to face opposition by activists and officials in some areas. U.S. critics of the company say the service is driving up rental market prices in several cities. Elected officials in some areas have proposed or approved rules to limit the influence of the service. Hotel companies have also protested that the business presents unfair competition.
