The largest rocket explosion was a Soviet / USSR

This is a small clip of the Russian documentary "Царь Ракета: прерванный полёт" (Translation: Tsar rocket, the interrupted flight) about the N-1.

Expect the full documentary to come very soon (+ with English subtitles).

Impressive how such a giant piece of engineering can be fully destroyed in seconds, also what was the cause for the engines to turn off?
