Which, although technically correct, is still quite misleading and misses out the fact that this was done purely as a precaution, since the actual crack causing the failure did not come from a passenger window [0] but rather the ADF aerial square cutouts in the roof. These are what the photograph in the article shows, and the position is also highlighted in the diagram there. The 'square' passenger windows, as pointed out in the wiki link cited above, had similar corner radii (or smaller in some cases) to those of the Boeing 377 and Douglas DC-7 aircraft.
