How about this- Asks specific questions about flying 747's, demonstrates
reasonable knowledge and thought about CBW and dirty bombs, is disgruntled,
an outcast, and socially isolated -unable to succeed in his own country, now
ekes out an existence in a foreign country.

Thinks he alone is the only one who has the right answers and knowledge
about subjects on which he has absolutely no experience- is paranoid and
believes everyone else is out to get him.

Does this raise any red flags with anyone?
