Fun fact, since I see you're from Nigeria: I did 9/11 in Lagos. Was part of the team doing the initial restructuring of the electricity distributors for private sector participation, and our SAA flight was supposed to originate from JFK around 9:30 that morning, which it didn't...so the airline put me, my colleagues and a few others from our flight up at a place called the "Marriott" Hotel. I say "Marriott" in quotes, because it wasn't really a hotel, more like a converted residence. That was in the days when we still used landlines to communicate across the continent!
