The helicopter pilot who crashed on to the roof of a New York City building was not licensed to fly in poor weather, the Federal Aviation Administration said.The pilot, identified as Tim McCormack, died in the crash, law enforcement officials said."Pilots must have an instrument rating to fly in bad weather," an FAA spokeswoman said. "This pilot didn't have an instrument rating."An instrument rating requires about 100 or more hours of additional training on top of basic pilot training, CNN aviation analyst Mary Schiavo said.It helps pilots learn to fly without visual reference to the sky under instrument flight rules, by relying solely on instruments to "fly blind" in clouds or heavy fog under the direction of air traffic control, Schiavo said.At the time of Monday's flight, moderate to heavy rain was falling in the city, and visibility at Central Park was down to 1.25 miles. Winds were from the east at 9 mph.City officials said they were not sure what led the pilot to crash-land atop a building without a helipad.A typical afternoon inside the offices of a Midtown Manhattan skyscraper suddenly turned to chaos when the helicopter, 11 minutes into its flight, landed on the roof.The helicopter took off from East 34th Street Heliport about 1:32 p.m. Monday, New York police Commissioner James O'Neill said.Based on interviews investigators conducted at the East 34th Street Heliport on Manhattan's East Side, the pilot made statements that he believed he had a 5- to 7-minute break in the rainy weather to take off, according to a law enforcement source familiar with the investigation. The pilot did not refuel at the heliport, the source added.Once the pilot was in the air, he radioed back to the heliport and said he needed to return. The last time the pilot communicated with the heliport he conveyed he was unsure of his location, the source said.The pilot then flew around Battery Park on the southern tip of Manhattan, up the west side of the island and then, somewhere around the streets in the 40s, started to veer toward Midtown Manhattan before crash-landing, the law enforcement source said.McCormack had flown for American Continental Properties, the company that owns the helicopter, for five years, according to a company statement.McCormack received his commercial pilot's license in 2004, according to Federal Aviation Administration records, and he was certified as a flight instructor for a rotorcraft-helicopter last year.In October 2014, the pilot was flying a helicopter over the Hudson River with six tourists on board when a bird struck and broke part of the windshield, according to 2637

The CDC announced on Thursday that cigarette smoking rates in the United States have reached recorded lows with just 13.7 percent of the adult population smoking cigarettes in 2018. The percentage of smokers is just one-third from the number of smokers from 50 years ago. The CDC said that 19.7 percent of American adults used tobacco products in 2018. Cigars are used by 3.9 percent of adults; e-cigarettes by 3.2 percent of adults; smokeless tobacco by 2.4 percent of adults; and pipes, water pipes, or hookahs by 1 percent. The CDC said nearly 18.8 percent of tobacco users use two or more products. “This marked decline in cigarette smoking is the achievement of a consistent and coordinated effort by the public health community and our many partners,” said CDC Director Robert R. Redfield, M.D. “Yet, our work is far from over. The health benefits of quitting smoking are significant, and we are committed to educating Americans about the steps they can take to become tobacco-free.”While overall tobacco use has declined, e-cigarette use is on the rise, especially among young adults. More than 7 percent of young adults (ages 18-24) use e-cigarettes. According to the CDC, cigarette smoking is responsible for more than 480,000 deaths per year including more than 41,000 deaths resulting from secondhand smoke exposure. 1339
