We begin with the search for flight 370. A Chinese satellite has spotted something in the Indian ocean that may be debris in the plane. Remember the first image earlier this week. From an Australian satellite. Authorities thought it was debris. Now this new image. Roughly the same size. And the distance, about 79 miles. We have team coverage including your questions from home. Why no drones? First our team to search for that debris and we begin with ABC's David Wright. Reporter: From Pearce airfield. We're about to get onboard an Australian p3 or Ron. Take a closer look it shows what appears to be an object floating in an Indian ocean. An object of significant size. 73 feet by 42 feet. The image taken March 18, last Tuesday around noon local time by the clean nice. News of this tantalizing new lead broke dramatically with a piece of paper handed to the Malaysian defense minister while he was briefing reporters. The Chinese ambassador received satellite image of floating images in the corridor and sending ships to verify. Reporter: His excitement palpable. If not for that paper, the headline would have been another day of frustration. This is all I have. Reporter: Today's location is about 79 miles southwest of the last satellite images showing debris. The ones chasing onboard. That day we came up empty. They call this area the "Roaring 40." The current strong. The ocean constantly churning. Today even more so. A tropical storm is baring down reducing visibility. Whipping up waves and making it hazardous to fly. It is not just military planes. There are also several chartered jets helping in the search and on the surface of the water ships and at least two merchant vessels helping in this search. David. With this new satellite image you can only imagine the Payne for the families. Tonight ABC's bob woodruff. As we hear from the first time from the pilot who flew the plane on that route. Bob. Reporter: David this has been a difficult for the families. When they hear once again the debris has been located by satellite, they're skeptical. They have led to ups and downs. The anguish can be seen in the faces of the families. We met with the wife and kids of Patrick Gomes. Who is the chief sturd steward on the plane. Their desperate for some kind of answer. If it's in the ocean, it brings us closure. But we hope it's not a hijacking and it's not somewhere. Hopefully he's still alive and come back to us. Reporter: But the mystery deep deepens, and we talked to the pilot that flew that route. He wouldn't speculate but told us when he was in that cockpit, he was ready for anything. Mind is constantly moving thinking of scenarios to save the airplane and preparing for the worst. Reporter: But if pilots are trained in extreme situations, families are not. Now the stress of the search on friends and relatives is relentless. Some family members have been rushed off to the hospital by ambulance when there is some new development. It has been a long painful road with a long way to go. Now to your questions at home still pouring in. So many of you tweet what you want answered. I want to bring in John nance, a pilot himself. Quite a few viewers asking about drones. Why not use a couple of predators. They can search in any weather, longer, over greater areas. What about drones John? There's no question a drone can do a better job and they do have cameras aboard. We have human eyes on the water. Because a drone will be take millions of pictures at least tens of thousands and a human has to go through them. If there's one on site you're going to be able to see that and that's the one you're looking for. The new image from the Chinese and the possible debris in the water. Win on the asking could the satellite have continued to track the debris until help arrived? If it had been real time. But the problem is we get three, four days after the picture has been taken and the satellite moved off. It's hoarding around at 17,000 mile an hour. At an orbit of about 150 miles. This is not like the satellite that can look down and constantly hover. Those don't have the capabilities. Our problem is time. John, this next question about the cockpit and the pilots themselves. Lew asking why is there no cockpit video recorder? Then we would be able to see what's happening during the flight. Absolutely correct. This is something that has to be changed. Although they have not wanted video in the cockpit up until now. We have to have it. It will solve several accidents at least over the next years. We talked about how deep the Indian ocean is. To what ocean depth is a black box capable of surviving with it's recorded date intact? There is no limit. Everything in the recorder is imprinted on a little chip and very well protected. Nothing in the way of water pressure is going to hurt it. John nance with us here tonight. Keep tweeting our questions. Use the #askworldnews. In the meantime we turn to
