Unexpectedly, a glitch with their flight computers caused United Airlines to ground an entire fleet of their 757 airplanes, causing several flight delays and cancellations at the last minute. United discovered a maintenance problem with their air data computers, which monitor critical parameters such as air speed and navigation. They mandated additional operational checks on all 96 planes, putting a hold on their flight schedules until the issue was resolved.
