From An Evening in Byzantium:
Meanwhile the terrorists have secretly taken control of three airliners and have landed them on remote and desolate airfields that have been prepared in advance to off load and imprison the airliners’ passengers and then quickly retrofit the planes to each transport and drop a nuclear bomb on three cities in the United States. These cities are Washington, DC, New York City, and Miami, FL. Bombs have been planted on three flying commercial airliners and set to detonate in flight so the terrorist controlled jets can impersonate the legitimate commercial flights.
That would make the final destination either Tokyo or Los Angeles.
