Even as his anxiety rose about American Flight 11, Boston Center air traffic controller Peter Zalewski knew nothing about Betty Ong’s anguished, ongoing call. No one from American Airlines’ Fort Worth operations control headquarters relayed information6 to the FAA’s Command Center in Herndon, Virginia, to FAA headquarters in Washington, or to anyone else. As minutes passed and commandeered Flight 11 flew west across Massachusetts and over New York, communications among the airline, the FAA, and U.S. military officials were sporadic at best, incomplete or nonexistent at worst.
