This was the 1st flight that brought back Americans that were in the war zone in the Mid East.
I think this flight from Manchester was the first, or at least one of, the flights. The news article I read said the first flight was arriving around 6:30 a.m. This flight arrived at 6:13. Given 15-20 minutes for taxying, this would have been right on the money.
The flight you mentioned goes from BWI to EDFH. I haven’t been able to find a flight in the reverse direction. It does sound logical that they may be flying from EDFH later today in order to bring back the people.
