Al, thanks. Now we turn to this growing concern over measles in this country. New numbers out from the cdc shows the outbreak has grown to 102 cases in 14 states. And now were seeing politicians entering the fray possibly at their peril over whether children should receive the measles vaccine that once eradicated the disease. Our report on that tonight from nbcs hallie jackson. Reporter an overseas trip is making headlines here at home after governor Chris Christies controversial comments on whether parents should vaccinate. Parents need to have some measure of choice in things as well. So thats the battle that the government has to decide. Reporter christies position weighing personal freedom versus Public Health raised eyebrows considering during the ebola scare he imposed a mandatory quarantine of a Healthy Nurse to protect the public. The quick backlash prompted Christies Office to walk back those remarks and clarify his support for the measles shot, as this Public Health conversation turns political. Ive heard of many tragic cases of walking, talking normal children who wound up with profound mental disorders after vaccines. Reporter but the vast majority of doctors say the shots are safe and so does president obama. Theres every reason to get vaccinated. There arent reasons to not. Reporter in new york an infected College Student may have exposed hundreds of commuters at busy penn station. And in california A Santa Monica day care says 14 infants under a year old will be quarantined for three weeks because of a potential measles exposure. Erin richardsons son is having a different experience at a different day school. Youre on day four, how has it been . Im tired of quarantine. Reporter her toddler, jaden, has had his first measles shot but since his condition may make him vulnerable to the measles anyway, doctors want him isolated. Every child that can be vaccinated needs to be vaccinated to protect the kids that cant, such as jaden. Reporter most states let parents opt out of vaccinations because of religious beliefs. And 18 because of personal reasons. Some people because of mistrust of authority, mistrust of the government. Some people just dont want to hear the correct information. Theyve made up their mind and theyre very stubborn about it. Reporter its why doctors are fighting this outbreak on a new front, the court of public opinion, to keep the Public Healthy. Hallie jackson, nbc news, phoenix. The white house is now considering arming ukraine against prorussian rebels, according to Senior Defense officials. Over the weekend talks over establishing a lasting ceasefire fell apart leading to the eruption of fierce fighting all over again in eastern ukraine. The u. S. Has stopped short of providing the Ukrainian Government with lethal force protection over the past year. Now to an nbc news investigation into an aircraft the u. S. Navy trusts with the lives of our Service Members in the course of a vital mission, the detection of underwater mines. Its the mh53e sea dragon helicopter. And its Safety Record is alarming. Dozens have been killed in these choppers over the years. Now in partnership with the Virginian Pilot newspaper and the berkeley investigative reporting program, our Senior Investigative correspondent Cynthia Mcfadden takes a closer look at why the sea dragons are still in the air. Reporter wes van dorn was a devoted family man. He loved his two little boys and he loved serving his country. The 29yearold lieutenant was a highly regarded naval aviator, pilot of an mh53e sea dragon, the navys largest, oldest and most dangerous helicopter. I think that its clear that theyre unsafe. Reporter his wife, nicole, says her husband complained to both his superiors and to her about the helicopters safety. In fact, this is a video he shot in 2012 of a sea dragon that crashed in korea. Was the navy asking him to do something that they shouldnt have been asking him to do . I think so. Reporter they knew that these helicopters werent safe . Well documented. Reporter indeed it is. According to the militarys own statistics, the sea dragon is three times more likely to crash than any other navy aircraft, and an astounding 30 navy men have died in sea dragon accidents. Built in the 1980s, theyre still in service 15 years after the navy started making plans to replace them. As the helicopters age, maintenance became a big issue, and what he saw frightened van dorn. It struck him to the core. Reporter he was afraid . Yes. Reporter and for good reason. Just over a year ago van dorns fears became a reality in a training night over the coast of norfolk, virginia. Old electrical wires chafed over a wornout fuel pipe and within seconds the smoke was filling up the cabin. Reporter dylan boone, a young sailor on board, described the explosion. 15 seconds, i believe, was by the time the fire erupted to the time we were crashing in the water. I know when i woke up i was about 20, 30 feet under water. Reporter would you want to go up in one of these sea dragons again . No. Reporter are they safe . I really cant answer that. Reporter boone and one other man survived. Van dorn and two others did not. Captain Todd Flannery was in charge of van dorns sea dragon squad run. Its a joy to fly. Reporter he took us inside one of the huge helicopters. Were you aware that he was concerned about the safety of the helicopter . I was not. Reporter because he did complain to his superiors about that he saw maintenance failures and a variety of problems to the aircraft. Right. It didnt make it up to me. He would have talked to his Commanding Officer with that. Reporter should you have known about his concerns . Yes, i should have. Reporter captain flannery says the navy had worked hard in recent years to improve safety and he believed the remaining sea dragons are safe. Im extremely confident in this aircraft and i would fly in it any time. Reporter is there anything that would persuade you this shouldnt still be flying . Another crash . I mean, how many crashes do we have to have . We cant have another crash. We just cant. It would be too late to be dissuaded then if we have another crash. Reporter five People Killed in four crashes. Yes. Reporter in the course of two years. Yes. Reporter those are odds i dont think most of us will want to take. Theyre not good. Those numbers are not good at all. Reporter in fact, nbc news has talked to three other navy air crewmen, who, in the wake of the van dorn crash, now refuse to fly the sea dragon. The only reason i am sitting here is because wes cant be sitting here because he started something that, unfortunately, i need to finish for him. Reporter japan has retired their similar helicopter, but to keep a sea dragon flying the u. S. Has been negotiating to buy their spare parts. Meanwhile, just two weeks ago in another incident a sea dragon was forced to land in kuwait because of electrical sparks inside the helicopter, brian.
