+1...and most likely it will be years, if ever, that we find out what really happened, or before any concrete information emerges. You are however correct, we do know now that it is entirely possible to fly a commercial airliner into a black hole, and make it disappear, while the world, with all it's experts stare at each other, like deer in headlights.
I'm not much of a conspiracy theorist either, so I won't even try and guess if this plane is at the bottom of the Indian Ocean, spread across some remote landscape somewhere, or safely on the ground, but what I have learned in the last few days, is most disturbing, and I can't even imagine what the loved ones of those on the plane are going through....
If nothing else, this has been a real eye opener, and hopefully a game changer in how we decide to track aircraft...though when all is said and done, I doubt much will change, because it's always about the money.
