Raketa slijetanje povratak SpaceX: prvi orbitalni pojačivač na kopnu

Dokumentarac prati kako je 22. prosinca 2015. Falcon 9 Flight 20 prvi put u povijesti doveo orbitalni pojačivač natrag na kopno uz dvostruki zvučni udar nad floridskom obalom. Kroz fiziku silaska, razvojne testove od Grasshoppera do Block 5 i četiri neuspjela pokušaja slijetanja, film objašnjava što je stvarno bilo potrebno riješiti. Na kraju uspoređuje noge i Mechazillu te bilježi što u ponovnoj upotrebi raketa još uvijek nije dokazano.
