This is the strangest event I have been made aware of in my 55 years of life.
This is an ultra-headscratcher...
I think it is time to print a picture of the plane on milk cartons to see if anyone in the public has seen it. That might turn up some leads.
Peep. I remember Judge Crater...LOL!
This plane would be located in a heartbeat if an IRS audit were ordered on the American IBM exec.
My folks told me the story of the disappearance of Judge Crater when I was into Sherlock Holmes in the 50s. After reading a little bit about it, I decided that Crater crossed Tammany Hall and paid for it. However, it kept me going for months. Amelia Earhart was the missing plane mystery. Then there was/is Jimmy Hoffa.
This missing airliner beats them all thus far in strangeness. My speculation well has gone dry.
Therefore, the plane did not fly until it ran out of fuel, aka Payne Stewart. It either crashed or landed after hour four.
I was thinking the same thing today, and I go back just a few years more than you.
Sounds like a Tom Clancy Novel.
Terrorists steal a plane, pack it with a NBC weapon or a EMP type and flies it over a US City, Maybe New York or DC.
The only thing is that in a Clancy Novel, the CIA is on the ball.
