Northwest Airlines Flight 188

[2] The incident also caused American lawmakers to move to prevent pilots on U.S. airliners from using personal electronic devices while taxiing or flying.

At the request of the Minneapolis ARTCC, Northwest's dispatchers made at least eight attempts to reach the pilots and urge them to reestablish radio contact, without success.

[8] Just as the fighter jets were about to scramble, air traffic control at Minneapolis-St. Paul International Airport reestablished radio contact with the plane at 8:14 p.m. CDT, by which time the flight was over Eau Claire, Wisconsin, roughly 100 miles (160 km) east of Minneapolis.

Captain Timothy Cheney and first officer Richard Cole said that they were not aware of their location until a flight attendant asked them what time they were due to land.

[2][7][10] One issue of particular concern was the delay, exceeding an hour, from the time air traffic controllers realized the plane was out radio contact until an alert on the Domestic Events Network (DEN) was created and NORAD was informed of the situation.

[11] An updated FAA notice effective November 10, 2010, called for an alert to be made within five minutes of last recorded radio contact.
