For those who’ve worked 747s, like I have, check out the staircase in the back through which most of the passengers entered, starting at 6 minutes. On a regular 747, this would be cargo, and there wouldn’t be stairs.
Also, after the captain made the turn to line up with the runway, he didn’t stop, but just kept right on going on into the sky. And it didn’t take much runway either, having a lighter load than most commercial 747s.
