Why do you keep saying it was dark? The article clearly states her flight was later in the afternoon of March 8.
Also:
“The Kuala Lumpur wife was so convinced about what she saw at 2.30pm on March 8, several hours after MH370 vanished, that she filed an official report with police that very day” Why are you saying she waited for seven days?
So let me get this straight:
She says she saw a plane in the water 12 hours after it would have passed by there. So it would have had to be bobbing in the water for 12 hours for her to have seen it.
A Boeing 777 is not going to float for 12 hours.
