| Oct 2 at 9:28 | comment | added | Mark Jones Jr. | This answer would be stronger with a reference that shows early aviators understood your comments about the quality of the wood. Scientific American suggests that walnut was used because it was common, and oak was simply a more economical replacement. The same article suggests that the glue holding the layers together was "not water proof." scientificamerican.com/article/… | |
