Sen. Claire McCaskill (D-Mo.) dismissed the idea that allowing airline passengers to use electronic devices during takeoffs and landings could distract them from hearing safety announcements on Tuesday.

After being pressured by McCaskill and other lawmakers, the FAA began studying easing its restrictions on electronic devices, which are currently banned completely when airplanes are below 10,000 feet.

The Missouri lawmaker said Tuesday that she doubted passengers would be less likely to pay attention to safety announcements if they had use of their electronics. 

"I've never had a flight attendant say 'put down your copy of War & Peace,'" McCaskill said during a hearing of the Senate Commerce, Science and Transportation Committee. 

All American Airlines flights are being held on the ground because of a system-wide computer error, the company said Tuesday.

"At this time, we are in a system-wide ground delay that will last until 4:00pm [Central Time] as we work to resolve this issue as quickly as we can. We apologize to our customers for any inconvenience."
