Jaw-dropping footage showed the moment a massive explosion blew apart a Queens home Thursday morning — knocking responding NYPD cops off their feet.

Officers were at the door of a South Ozone Park home for a domestic dispute and trying to get inside with a set of keys when the Hollywood-style explosion ignited and lit up the predawn sky, according to bodycam video released by the NYPD.

Cops helped each other to their feet and into the street in the aftermath with an officer heard saying, “The guy just lit the house on fire. We have explosions.”
