You are absolutely correct!

However, the 747 is not as large as the 380.

My interpretation of the cracks is that the 380
lacks the sophisticated design of the 747; and
its components, from a microscopic point of
view, that is, the molecular adhesion aspects,
are fundamentally insufficient.

Metal has a finite adhesion value.

Exceed that value and a tiny crack becomes a
big crack.

This change happens suddenly, like most mass effects
on Planet Earth.

I advise my readers: Don’t be there!

I may be wrong, but I prefer to err on the side of safety.

Excellent point. But it is not larger than the 380.
In my opinion they should have stopped with the 747.
I think the design of the 747 is excellent, and had
the designers thought they could have made it bigger,
they would have. But they did not.
Why?

Excuse my misperception of relative sizes but the 747 has been in service since its inception and is larger than concorde or theDC10
