Disrupted air travel along the heavily populated U.S. East Coast was resuming normal operations on Saturday after the U.S. Federal Aviation Administration said it had fixed an automation problem at an air traffic center that led to hundreds of flight cancellations.
The FAA said an air traffic center in Leesburg, Virginia was thought to be the cause of the issue which canceled more than 440 flights for hours and caused hundreds of other flights to be delayed during the busy August travel season.
The FAA said it was working with carriers to resume normal service and that the problem "has nothing to do with an accident or hacking."...More than 440 flights were canceled at airports along the U.S. East Coast on Saturday, according to flightaware.com, a service that tracks global air service...
"The FAA is continuing its root cause analysis to determine what caused the problem and is working closely with the airlines to minimize impacts to travelers," it said in a statement.
THERE CANNOT BE TOO MANY REASONS FOR THIS FAILURE...AND THEY ARE ALL OF HUMAN AGENCY. I'M GETTING OUT MY TINFOIL....
1. BAD SOFTWARE UPGRADE
2. HACKER (DESPITE DENIAL)
3. WORKER SABOTAGE (PERHAPS INADVERTENT)
IN HYPOTHESIS #1, IF IT WORKED FINE FOR YEARS, WHY WAS IT CHANGED? SO THEY COULD FIRE A HUMAN OR TWO?
