Conduct routine tests for Treasure Island. He said the navy didnt expect he would find anything. As youll hear tonight, that was not the case. When you first arrived in 2007, the navy said this was no Radioactive Material on Treasure Island. Correct. Reporter what did you find . Reactive material. Reporter Don Wadsworth is a radiation expert. His company has worked many military cleanups of radioactive sites including Hunters Point and the navy bombing yard. In 2007 wadsworth and his team at new World Environmental were hired to work at Treasure Island where they are still working today. When you first got to the island, what was your job . Perform surveys of areas being excavated for treatment for chemical contaminations. Reporter wadsworth said his surveys found significant amounts of radiation throughout the island. In your professional opinion, should people be living at Treasure Island . No. Reporter can you explain why . Well, just from these pictures youve shown me here, youve got a significant contamination level. Reporter hes referring to this picture obtained by the Investigative Unit from a navy report released to regulators last month. It shows radiation readings taken on big low court. A building that has never been released to residents because it is a known disposal site but wasnt until this year the navy identified it on this map as being radiologically impacted. Wadsworth said it is an example of the navys reluctance to reveal the nature and extent of radiation on Treasure Island. Do you feel the navy has actively tried to cover up this information . I really dont have a way of knowing what theyre doing. But certainly, it does appear that way. The information that we get from the navy is all denials saying everything is fine and theres nothing to worry about. And we havent found anything that is alarming at this point. Reporter paris and cindy hayes have lived on the island for 11 years. There are two dozen families who were abruptly informed they have to move in april. They told us that our relocation was based on the fact that the navy needs to do more surveillance. On the property. But it was not related to any Radioactive Material findings. Reporter in this map, the hayes building and 5 other buildings were recently identified as on or near areas of radiological impact and like Bigelow Court now need to be surveyed for radiation. There is not evidence of radiological materials being buried where people are currently living. Reporter Treasure Island director bob beck. How would you characterize how trait forward the navy has been with residents in informing fwhem the radiation here on Treasure Island . I think theyve been extremely straightforward in informing them. Reporter is there any radiation where the folks are being asked to move out . We requested an interview with the navy cochair but his office said he was not available. We tried to speak with him before a public meeting. Youre sbrumting the introduction of the meeting. There are meeting doesnt start for another 15 minutes, sir. Thats not true. The official part of the agenda starts at 7 00. Prior to that we have a holiday session here. And youre interrupting that. So please refrain from interrupting. Youre not able to answer any questions during the potluck . I said thank you. Good. Reporter it has been a frustrating ordeal for the 2,800 people who live and work on Treasure Island. Whose voices have grown louder as more information surfaces. Contradicting the navys claims about the contamination. So you come here and you tell us what you want us to hear. But i think you need to go back to whoever it was and let them know that they are no longer buying it. Reporter the contractor said six years into his work at Treasure Island he has this assessment. My job is to protect people and the environment. And so it is not getting done. Reporter the navy provided the Statement Today reaif i recalling that it is working with regulators to, quote, investigate and clean up contaminated areas on Treasure Island, and that the state, city and navy do not have any data confirming the risk to Current Health of the residents.

Then hearings on the deadly asiana crash at sfo. New details about what went wrong. Plus, exposed. He was supposed to deliver a speech. What his gestures are sparking outrage. You are looking at new video the ntsb released today of the crash landing of flight 214 this past july. You can see the passenger jet hilt the ski wall, skid across the runway and come to a stop. Weve been out in front of the story from day one looking into what could have caused the massive 777 to crash. Heres more on what experts say went wrong. Reporter according to paperwork evidence as part of the hearing, the 43yearold pilot who was in charge of thanning the plane told investigators he was worried about landing at sfo before the crash. All because the electronics glide slope was not operational even though it was a clear day and he was flying under visual flight rule. The video shown in the investigative hearing room of asiana flight 214 hitting the seawall short of runway 28 left, cart wheeling down the runway served as a sober back drop as the ntsb explored what happened before, during and after the crash. A wall of fire within 47 minutes. Reporter the main focus of the three of the four expert panels to testify involved a growing issue of overreliance by pilots on auto pilot and auto throttles in the cockpit. And how that may have played a role in this crash. We identified vulnerabilities in that the pilot sometimes rely too much on the Automated Systems and may be reluctant to intervene. Reporter several witnesses described the confusion in the cockpit of the boeing 777 in the final seconds before it crashed at sfo. The pilot is the final authority in the operation of the airplane. We try not to put in Design Elements that can override the pilot. Other testimony made clear that asiana pilots may have been confused thinking auto throttle thats they had set on hold would automatically wake up and increase the planes speed if it got too slow. Instead, that did not happen. We do have an issue in aviation that needs to be dealt with with respect to automation and performance when it comes to the interaction between the aircraft and the human being. Several experts testified that the train pilot should have been able to see from the planes pitch altitude and vertical speed they were going too slow and were too low. If you fly level or less, i would think that would cue him that he is flying slow. We design the airplane to assume the pilots will fly the airplane. Ntsb Board Members will now take all this evidence and begin to analyze it to try to come one the final formal cause of the crash. It is a process likely to take several more months. A decision could come as early as this summer. Thats the latest from washington, d. C. Nbc bay area news.
