I have trouble believing the CWT story, but I also have trouble believing the Navy would be firing missiles into a known traffic pattern of a large airport like JFK. They have plenty of off-limits airspace to do that kind of thing. The terrorist missile story is also weak since they are not normally any use up to the altitudes in question. I'm not sure what to think.
They weren't firing into the traffic pattern.
The anti-missile missile went off course and locked onto the big jet.
