I doubt it.
The media would have just labeled it "an accident" or "mechanical problems," and no one would have known about the terrorist plot (if all on board had been killed).
Thanks to that brave guy who tackled the perpetrator, 300 people are still alive today, and we have hard EVIDENCE that it was a terrorist act (although the Obama administration is loathe to call it one).
Yeah, you’re right, they’d be withholding news of the chemical tests proving an explosive was used.
And that one of the passengers was on the watch list and his father had told the CIA he was fanatic.
But eventually the truth would have been leaked. And then finally Janet would have left for personal reasons.
Meanwhile, Christmas and the end of Obama’s first year would have been under a cloud; and people would have been upset and suspicious that he and his corrupt administration were withholding info and failing to do their primary duty to protect us.
The same 'info' about the Nutty Nigerian would have been available, and I don't think they would have been able to keep it under their collective MSM hat.
