What I'm saying is people will immediately shut down listening when you start talking about the twin towers. They've been conditioned to think you are crazy because "such a tragedy how could you". I do I worked in the industry. When asked about the calls by fellow engineers and installers the spokesperson for at&t said "I guess it was just a miracle" and refused to answer any more questions. Try to make a call if you are ever on a plane. Even if you don't crash the system it will cut out almost immediately.
