I dont understand how in this day and age a Boeing 777 can drop out of the sky and leave no clues as to where it is.

I see a bunch of speculation from the news agencies regarding the Iranian passengers who used stolen passports to board the plane bla bla bla.

I wonder if its possible that the plane was hijacked, and then was flown low enough as to not appear on radar and landed in some hatred filled country. Like North Korea for example.

Is this possible?

Anyone here have any ideas on what might have happened here. I fly a lot and its beyond me that this can happen.
