I used to have all of the original footage from that disaster including all parts that were edited out. Sadly, it was itself the cause of another near-disaster. The film was nitrocellulose, which becomes unstable with time. The film canister burst into flames, incinerating it and several other old films that were stored with it. It sounded like ammunition cooking off as it burned.
