Yup. I wanted to make clear what you were doing.

Also, in this case, mass is directly proportion to surface area. Reducing the mass (exclude the windows) also reduces the surface area by the SAME FACTOR.One more thing. Man made lasers have heated aluminum to over 3 million degrees. 20,000 degree Celsius is nothing compared to that. So I don't see how 20000 is overly optimistic. It's really a gross lowball estimate. I didn't even include the mass of the stringers and formers (which add significant more mass of aluminum).
He cut the plane at 60 degrees. That means the length of the cut is significantly bigger than the height of the plane. Again more mass.The thickness of a plane's skin can be over 2 mm and about 1.4mm average for smaller planes. I used 1 mm. That's 40 percent less mass I used.
Lastly I assumed he just heated the aluminum to 660 (the beginning of being melted) when in reality it could have been heated to over 1000 degrees.
I took liberty to lowball every number instead of at least using averages.
Wut. I see you're doubling down on your error now, let me explain:
Mass is proportional to volume, not surface area, and it NEVER is unless you're having a uniform lamina. Which you're not. So it's not.
