the existence of the Soviet device, he agrees to Bradley's proposal that they work on the "theoretical application" of how a "theoretical" Soviet space platform's weapons would be coordinated with the American platform. Meanwhile, more meteorite fragments strike Earth (one inside Siberia), and the Soviets finally agree to join in the effort. Both satellites are coordinated, and turned towards the incoming large asteroid as smaller fragments continue to strike the planet, causing great damage, including a deadly avalanche in the Swiss Alps and a tsunami which devastates Hong Kong. With hours remaining prior to Orpheus' impact, as planned, Peter the Greats missiles are launched first because of its relative position to the asteroid, with Herculess missiles timed to be fired 40 minutes later. Immediately prior to Herculess missiles being launched, a splinter fragment is discovered to be heading towards the command center in New York City. If the center is destroyed, Hercules will not be able to launch. With seconds to spare, Hercules receives the signal to fire from the command center, and launches its missiles. The splinter impacts the city, destroying the top half of the World Trade Center twin towers in a direct hit, and creating a large crater in Central Park. Several workers inside the control center are killed when the facility is partially destroyed by the collapse of the building above, and the survivors are forced to work their way out of the control center by going through the New York subway system, which becomes a trap due to water from the East River flooding the tunnels. Meanwhile, the two flights of missiles link up into three successively larger waves. The Hercules crew reaches a crowded subway station and waits while others try to dig them out. Eventually, the missiles reach the meteoroid. The first wave of missiles strikes the rock, causing a small explosion, the second wave follows with a larger blast, and the third wave creates an enormous explosion. When the dust clears, the asteroid appears obliterated. In New York City, the radios broadcast the good news: Orpheus is no longer a danger to Earth. Just then, the subway station occupants are rescued. Later, at an airport, Dubov, Tatiana, Bradley and others exchange goodbyes before Dubov and Tatiana depart on a plane for the Soviet Union.
