Then of course some consideration has to be given to possible interpretations
by passengers. If an ailine unthinkingly assigns a Flight 666 you can be sure
some whacko will firebomb the airline.

The companies themselves don't seem too superstitious about it though -
after the Delta tragedy in DFW, American didn't hesitate to to assign Flight
191 - I'll bet that number is not used much these days!
