Oh yeah buddy!
Yesterday while wasting some time - I searched Youtube for some tips on TIG welding aluminum... I came across some "interesting welding" - one of which showed a guy using a torch on the bottom of a beer can - and then doing a technique that "back in the day" I'd have called brazing... adding filler and smearing this filler around until the hole was patched.
Looks like the repairs here used a similar technique...
I'm ASSuming that the airframe is aluminum?? I don't know anything about planes except that I'd never jump out of a perfectly good one.
