I notice the presenter said repair patches were soldered on, I don't think so.
We'd usually put what we called 100mph tape ( or was it 200mph?) on holes in the outer skin, then later a pop rivet patch. But if it also punchered a stringer or other structure underneath it would get repaired by real rivets, buking bar and all.
A hate to think what heating aluminum to solder it would do to the temper.
That presenter just didn't know her subject matter as she should have.
