Computer equipment went on the fritz at Delta Airlines this week. Tens of thousands of passengers and employees were affected by more than 1,000 canceled flights and 2,800 delayed takeoffs.
No doubt the problem was extraordinarily costly for Delta and at least some of the affected travelers.
What happened — entirely as a result of equipment malfunctions — is a reminder of how critical it is for U.S. officials in both the private and government sectors, to improve the security of computer networks.
What occurred was bad enough. Imagine if it had been a cyberattack by someone intending to cause chaos.
