Titanium Sandwich

A Net Flicks candidate is former US Air Force Lockheed SR-71A Blackbird 64-17960 preserved at Castle AFB Museum, California

 

A product of Lockheed's infamous 'Skunk Works', Kelly Johnson and his team solved the problem of generated heat by constructing the aircraft using both Aluminum and Titanium 'sandwiched' together

 

One thing that the SR-71 never suffered with was metal fatigue as every time the aircraft flew, the structure actually became stronger
