Professor Vikrant Vaze is quoted in a story about a technical system failure in Delta’s hub of Atlanta resulting in 4,000 canceled flights:

"'Without data, it’s really difficult to study this,' Vikrant Vaze, an assistant professor of engineering at Dartmouth who has researched airline-caused delays, told BuzzFeed News. 'Nobody tracks it.'

"Still, headlines suggest that airlines are struggling as a result of computer-related issues, Vaze said. 'Anecdotal evidence suggests that the resiliency is lower than what it should be.'"
