Didn't think this could happen, at least with a company such as Delta.
Well, lets see.
When DAL first started transAtlantic service, gross navigational errors were common...for awhile.
Then, about a dozen years ago, one of their DC-9's landed in gusty winds, and dragged a wing tip.
The airplane was taxied straight to the hangar, and the incident was not reported to the FAA for three days.
Fact.
...radios are unlikely tuned
Big mistake.
