Currently, Flight 23 is from JFK to LAX with a scheduled departure time of 8:55 am.
My husband had a business acquaintance who was scheduled to fly from Toronto to San Jose/SFO (can't remember which...) that morning-9/11. His plane was grounded and he told my husband that there were 3-6 'suspicious' types who deplaned and disappeared (i.e. no attempt to reschedule/make other arrangements as all the other passengers were trying to do). Coincidence? Perhaps.....
