bomb on board

heyyyyyyyyyy everybody.. so sorry was away for a long time because i was a little busy at that time...
as i remember 8 years ago in the year September 11th 2 planes hit the world trade center.....
One plane hit the pentagon and the other crashed in a field (united 93)
even though i was 9 that thing devastated me.. and i guess it really affected the goverment in ways that we cant imagine.. a few years ago terrorists tried to bomb flight heading to usa from LHR (London heathrow) but shouldn't the government take extra measures and policy like i dont know.. u mmmmmmmmmmmm like "NO BOMBS IN THE AIRPLANE" but yesterday a passenger from Nigeria tried to explode a bomb in the airplane...apparently he brought an entire laboratory in the airplane.. he kept making the bomb in front of passengers.. and that guy assumed that the passengers would keep on smiling until the bomb would just go off....but how could a guy bring a bomb on board?.. and that wasnt just any plane.. infact that was like a wide body jets which could hole upto 250 passengers!!! .... didn't the people learn the from the last two incidents?
i thought that the government be some kind of a mastermind.............. and i thought that terrorists were like some super genius.... obviously they weren't ..
So actually won in the incident of the delta air incident?
the terrorist?
or the national security?
only time will tell :)
