AAIB report
It may well have been the case that the client had called the DATCO at the time. I am not privvy to what he had said in his report. The DATCO at the time would have not had authority to declare open before 0800. The DATCO did indeed call me to see if we could open to accept the flight , but as I understood it, it was a request from radar in the seconds before impact and that was when he, the DATCO asked me if we could open and accept him. We were not open prior to that communication with the DATCO.
