OMG! That’s awful :-(
The 747 is a very safe aircraft.... must have been some kind of cargo shifting around or something similar. It almost looks like it turned from an aircraft into a non aerodynamic blob that just fell from the sky.
Pretty good description of a stalled airplane I'd wager. If it is not flying, it is a a brick.
Interesting your description of the 747 in free fall. I understand that the First Lady goes by the acronym, NAB.
