You can't just say that "because it's a 747, it can fly":

A 747 with no fuel can't take off and fly.

A 747 with so much load that it never takes off at all, can't fly.

And IMHO, a 747 with just so much load that it can barely take off but can't get out of ground effect, also can't fly. It's borderline, but not really.

It's an academic distinction though. Give the 747 a while, and it will burn enough fuel to lighten and ascend.
