For the last three weeks,everyday there's been constant new coverage about that attempted Christmas Day terror attack. There's also been nonstop coverage of new changes in security. Naturally all of this will cause increase travel & flying anxiety in many people.  For all the failures in security, the only positive thing that I found reassuring is ever since 9/11 passengers have decided that they will not go down easy when it comes to terrorism. There have been several flights in the past couple of years where you had either a disrupting passenger or an attempted breach of cockpit & other passenger helped the flight crew to contain the situation. We seen this once again on the Northwest Detroit inbound flight on Christmas day. Security is everyone's business & when the public, government, & airlines work together this increases everyone margin of safety.
