Your problem is that you require that the TSA be responsible for catching them. The two I know off-hand from popular culture are: http://en.wikipedia.org/wiki/Richard_Reid http://en.wikipedia.org/wiki/Umar_Farouk_Abdulmutallab

Found a better list here:

  * American Airlines Flight 63 The "shoe bomb", a failed al-Qaeda PETN bombing attempt in December 2001.
  * China Northern Flight 6136, a 2002 flight brought down by a passenger who had purchased life insurance, who set a fire in flight with gasoline
  * 2004 Russian aircraft bombings Islamist terrorist attacks on two domestic Russian passenger aircraft flying from Moscow. The bombs were triggered by two female Chechen suicide bombers. Shamil Salmanovich Basayev militant leader of the Chechen terrorist movement claimed credit.
  * 2006 transatlantic aircraft plot al-Queda terrorist plot to detonate liquid explosives carried on board at least 10 airliners travelling from the United Kingdom to the United States and Canada. It followed the same general plan as the Bojinka plot.
  * Northwest Airlines Flight 253, the target of a failed al-Qaeda PETN bombing attempt in December 2009
  * 2010 cargo plane bomb plot, failed al-Qaeda PETN bombing attempt on two planes in October 2010

ETA: I want to note that my issue is only that you stated a factual incorrectness: that no terror attacks have occurred involving airplanes in the past 11 years. You can denigrate the TSA all you want; just do it based on factually correct statements.
