Cellphones a Danger on These Boeing Jets

U.S. government officials in 2014 revealed an alarming safety issue: Passenger mobile phones and other types of radio signals could pose a crash threat to some models of Boeing 737 and 777 airplanes.

More than 1,300 jets registered in the U.S. were equipped with cockpit screens vulnerable to interference from Wi-Fi, mobile phones and even outside frequencies such as weather radar, according to the Federal Aviation Administration, which gave airlines until November 2019 to replace the units made by Honeywell International Inc. Honeywell estimates that 70 or fewer planes with cockpit screens in need of repair are still flying.
