This has happened at Ellsworth in the past...many times as a matter of fact going back to the days of Frontier, NWA and maybe WAL. The airlines have used Ellsworth as an alternate in the past and even operated out of Ellsworth while the runways were under construction at RAP. Assuming the tower was in operation at this hour, once has to wonder why the controller did not call out this impending error to the crew. Anyone who has worked this ATC at RAP is keenly aware of the impending situations that occur at RAP?
Nothing to see here other that perhaps some time off for the crew.
