Lawrence Ari Fleischer, Press Briefing by Ari Fleischer… (2001)
“ What kind of state of alert is the White House had, and law enforcement, about people who may still be flying, that may be a danger? And, secondly, has the President rescinded the order for the military to shoot down commercial airliners, if necessary? MR. FLEISCHER: On the second point, I'm not going to address the exact status of the defense operations to protect the American people. Suffice it to say the United States remains on a very heightened status of alert to protect the traveling public. ”
