In Vice (2018), during the 9/11 terrorist attacks, the Vice President, Dick Cheney, asks Rice:
Dick Cheney: Let's make sure those phone lines are working.
Rice: Phones are go, sir.
Dick Cheney: The SVTC. Let's contact the FAA, find out how many planes are in the air.
Rice: Yes, sir.
Why did Dick Cheney say, "The SVTC"?
