They recovered four, three of them AT the crash sites! How. The black boxes didn't even survive. 
What people? Americans? You can show them Jesus and they’ll ignore you. The rest of the world? None of them cares because who gives a shit that 3000 Americans were killed? How many of their countrymen were killed by Americans? What’s lib shit is obsessing over a handful of Americans dying. The psyche of America won’t be change unless similar events happen again. The truth won’t matter.
