Transcript for Trapped crew members rescued from capsized cargo ship
that daring rescue of four sailors trapped inside a massive cargo ship that went aground off the U.S. Coast. The ship toppling onto its side off the coast of Georgia, catching fire. They had rescued 20 before, but were turned back because of fire. The four sailors were feared lost and then today, sounds heard inside. And a response team drops in by helicopter, cutting through the hull and finding the men alive. Throughout the day, the struggle to get them out. Tonight, all four are now out. They are okay. ABC's Kaylee Hartung on the scene in Georgia. Reporter: Tonight, the desperate rescues at sea. Emergency response teams on the hull of that massive overturned ship. One of the crew members on a stretcher, lowered to safety. Another seen smiliing after a grueling 30 hours trapped inside horrifying conditions.

The longer this ship stays out here, the greater the environmental concern. We're a half mile from it on the trip out here, we were driving through pools of oil and you could smell it. Experts say it could take weeks or months to turn over the ship and remove it. Kaylee is with us live now. We can see the ship behind you. And we know some eyewitnesses say the ship appeared to be listing when it left port? Reporter: That's right, David. This ship had just dropped off half of its automobile cargo in this busy port.
