Did you hear the part were the FAA guy trys to explain why none of the controllers were tested for drugs or alcohol? He basically said “ we have to review the tapes first to see who needs to be tested”. Would’nt that be a bit too late?
IIRC, a commercial pilot cannot consume alcohol for at least 8 hours before a flight. Some airlines it’s 12 hours.
You would think an ATC would be the same regulation..............
