You mean the plan was empty because all I wanted was the photo op of the plane leaving?
I read that in fact some planes did leave empty during the beginning of the evacuation.
Leaving empty and leaving with vacant seats are two different things.
And remember the C17 is a cargo plane that is how they got 800 to 900 people on board.
Here is a photo.

But remember, those planes cannot stay at the airport for a long time without risk of damage. It is a war zone. Talibunnies are all around the airport and Al Qaeda is present to some degree.
This is not “as seen on TV”
