The wooden Luftwaffe fighter undone by a glue factory

Germany's Focke-Wulf Ta 154 Moskito was a largely wooden fighter, built that way to save scarce metal. Its development was reportedly hampered when bombing damaged the factory that made the wood glue. A fighter whose strength depended on adhesive turned out to depend on one fragile supplier, which is a lesson in supply chains older than the phrase. A newly shared photo shows the aircraft in hydraulic testing, a reminder of how much engineering went into a plane that never made much of a mark.
