US: Officials say Vegas air controller who went silent has resigned

An air traffic controller who became incapacitated during a solo stint on a night shift in the tower at busy McCarran International Airport in Las Vegas last week has quit, authorities said Tuesday. The unidentified controller was no longer employed by the FAA, the agency said in a statement. The controller resigned Sunday, said Benjamin Rosenbaum, an aide to US Rep. Dina Titus, D-Nevada. Titus is a member of the House Subcommittee on Aviation and represents Las Vegas. The congresswoman said Friday she wanted answers after an initial briefing about what she called the "deeply disturbing" Wednesday night incident. Officials have not identified the controller or said what caused her to slur words during communications with pilots over a 40-minute span before the FAA said she "became incapacitated while on duty" and apparently lost consciousness shortly before midnight.<br/>
