The two Helicarriers extended a total of thirty-eight aerial cannons from the clouds. Each cannon was half the size of an armed helicopter, with more than sixteen rotating barrels spinning madly. Seventy-millimeter rounds rained down on the Triskelion Building at a fire rate of eighteen thousand rounds per minute—one hundred and sixty-six rounds per second. Thirty-eight straight lines of fire formed amid the clouds.
