Its at the bottom of the sea.........
I use ACARS most days when Im working, if I want to make my Aircraft Invisible I can do it in 4 button presses......Civilian Air Traffic dont have a green screen with blips on anymore its all very clever Mode S databurst, static antennas....ATC now know which buttons I press at 43,000 feet
Hijacked, ran out of fuel, Hypoxic Crew, high speed impact.....if you're really bored and want to waste 3 hours of your life you will NEVER get back then have a read. Theres thoughts that it may be sat at an airport somewhere undetected.......
In which case the 240 Souls will either be
dead on board in which case it wont be going anywhere soon as it will be quite smelly
alive and the hijackers will be sorting 720 meals per day and a van full of water every 12 hours
dead in a pile 60 feet high visible by satellite or buried in a trench 150 meters long....
Apologies for my scepticism!
