On 2017-01-03 DAL58 from Boston to London apparently returned to New York after 90 minutes of flight.
This seems quite irregular to me, and I had expected to find details about this published somewhere. I tried Google, and I searched at avherald.com for the date and also for B763, but didn't find anything.
Was this not sufficiently irregular to warrant some kind of public information about what happened on this flight? Or if such information is published, where could I find it? Or is such information only available to certain people?
