Stephen: Russian jet crash may be another 9/11

Hi, I am an American and my concern today is the jets that were hijacked. It sounds like terroism, another 9/11 in a different country, but why and does not your country have the video tapes of the passengers that all boarded the planes.
As I know here in America that was key to who boarded the planes and solved our mystery of who well this is not good news for anyone god only knows the motives for these sick crimes against humanity.

Well good day.
Stephen
