Hmmmmm.....strange.....
Oh wait, what’s that smell? Could it be a muzzie?
“Could it be a muzzie?”
That’s what I’m thinking. Japan isn’t too hot on that bunch. If he had landed on Japanese soil, half of the Western media would have shown up, along with every Western lawyer possible. They would have demanded that he be permitted to bring his family over. Of course, in that culture, ‘family’ can extend quite wide, as in about 1.5 billion people.
It couldn’t end well for Japan, so they told ANA they wouldn’t be permitted to land there, and they’d have to find another airport, or ditch. So they went back.
Just a mistake in pre-screening, in that case.
